Digital Ecosystem Resilience as a Competition Policy Goal

1. Introduction

Digital ecosystem resilience refers to the ability of a digital market or platform ecosystem to continue functioning, adapt to technological or commercial shocks, preserve meaningful choice, and prevent excessive dependence on a single undertaking or technological layer.

Traditional competition law generally focuses on preventing conduct that raises prices, reduces output, lowers quality, or excludes competitors. Digital markets require a broader perspective because competition can be undermined even where monetary prices are zero. A platform may become indispensable because of network effects, accumulated data, interoperability advantages, switching costs, cloud dependence, app-store control, default positions, or ecosystem-wide integration.

Accordingly, resilience can be treated as a competition-policy objective, particularly where concentration creates systemic fragility.

The concept does not mean that competition authorities should protect every inefficient competitor. Rather, it means preserving the contestability, diversity, interoperability and substitutability necessary for digital markets to withstand the failure or strategic manipulation of a dominant ecosystem.

2. Meaning of Digital Ecosystem Resilience

A digital ecosystem normally consists of interconnected layers such as:

• operating systems;
• app stores;
• cloud infrastructure;
• search engines;
• online marketplaces;
• payment systems;
• advertising technology;
• data infrastructures;
• APIs;
• identity systems;
• AI foundation models;
• digital wallets;
• content platforms; and
• complementary applications and services.

An ecosystem becomes resilient when users and businesses can move between providers or rely upon alternative providers without prohibitive disruption.

Basic formula

Digital resilience = contestability + substitutability + interoperability + diversity − excessive dependency

Competition policy therefore asks:

What happens to competitive conditions if one technological gateway becomes indispensable?

If the answer is that competitors, consumers and complementary businesses have practically no alternative, resilience becomes relevant to competition analysis.

3. Why Resilience Matters in Digital Competition

A. Network effects

The value of many digital services increases as more users participate.

For example:

More users → more data/content → better service → more users → stronger ecosystem

This feedback loop can create self-reinforcing concentration.

A dominant platform may therefore become difficult to challenge even without continuously engaging in exclusionary conduct.

B. Switching costs

Users may accumulate:

• data;
• contacts;
• purchase history;
• reputation;
• digital credentials;
• subscriptions;
• application libraries;
• cloud configurations; and
• platform-specific skills.

Consequently, a theoretically available alternative may not constitute a realistic competitive constraint.

Resilience requires that users retain a practical ability to leave.

C. Interoperability

Interoperability allows competing services to communicate with the dominant ecosystem.

Restrictions on:

• APIs,
• messaging interoperability,
• payment access,
• data portability,
• authentication,
• operating-system functionality,

can make an ecosystem less contestable.

Competition policy can therefore treat interoperability as a mechanism for preserving resilience.

4. Resilience Is Different From Protecting Competitors

This distinction is fundamental.

Competition law should not ordinarily preserve competitors merely because they are smaller.

The relevant question is:

Does the disappearance or foreclosure of the alternative reduce competitive constraints or make the ecosystem structurally dependent on one undertaking?

Thus:

Legitimate competition

A more efficient platform defeats weaker rivals.

Resilience concern

A dominant platform uses control over an essential ecosystem layer to prevent rivals from developing viable alternatives.

The first is normally competition.

The second may undermine market resilience and contestability.

5. Dimensions of Digital Ecosystem Resilience

5.1 Structural resilience

This concerns the number and diversity of meaningful market participants.

Indicators include:

• concentration;
• market shares;
• number of viable competitors;
• entry rates;
• acquisition of emerging competitors;
• dependence on a single infrastructure provider.

5.2 Technological resilience

A resilient ecosystem should not depend excessively upon one technical architecture.

Relevant factors include:

• interoperability;
• open standards;
• API access;
• portability;
• compatibility;
• multi-cloud capability.

5.3 Data resilience

Control over data can reinforce ecosystem dominance.

A resilient ecosystem should permit appropriate movement of data between services, subject to privacy and security safeguards.

This connects competition policy with:

• data portability;
• interoperability;
• data access;
• data-sharing remedies.

5.4 Commercial resilience

Businesses should not become completely dependent upon one platform for:

• customers;
• advertising;
• distribution;
• payments;
• logistics;
• cloud infrastructure.

A small business that obtains 90% of its customers through one platform may technically have alternatives but may lack effective bargaining autonomy.

5.5 Institutional resilience

Competition authorities themselves need mechanisms capable of responding to rapidly evolving digital ecosystems.

This can include:

• continuous monitoring;
• merger review;
• market investigations;
• interoperability remedies;
• behavioural remedies;
• structural remedies;
• information-gathering powers.

6. Resilience and Market Power

Digital ecosystem resilience is particularly relevant to Article 102 TFEU, national abuse-of-dominance provisions, merger control and digital-markets regulation.

A useful analytical chain is:

Ecosystem control → dependency → reduced switching → reduced contestability → weaker competitive pressure → greater market power

The authority should, however, demonstrate the connection between the ecosystem characteristic and a competition harm.

Resilience should not become an independent justification for intervention disconnected from competitive effects.

7. Relevant Theories of Harm

A. Self-preferencing

A dominant ecosystem can privilege its own complementary services.

This can gradually eliminate independent providers.

The resulting ecosystem may become less resilient because users encounter fewer viable alternatives.

B. Tying and bundling

A dominant firm may condition access to one service upon adoption of another.

This can transfer market power between ecosystem layers.

C. Refusal of interoperability

A dominant undertaking may restrict competitors' access to technical interfaces.

The consequence can be particularly serious where interoperability is necessary for effective competition.

D. Exclusive dealing

Exclusive arrangements may prevent complementary businesses from participating in competing ecosystems.

Over time, the ecosystem becomes increasingly closed.

E. Killer acquisitions

Acquisition of emerging competitors can eliminate potential future sources of competitive pressure.

This is especially significant where the acquired firm has:

• innovative technology;
• valuable data;
• rapidly growing users;
• disruptive business models.

8. Case Laws

1. United States v. Microsoft Corp. (D.C. Circuit, 2001)

Facts

Microsoft possessed substantial market power in PC operating systems and was accused of engaging in conduct designed to prevent competing browsers and technologies from gaining distribution.

Decision

The D.C. Circuit found various exclusionary practices unlawful and recognized the importance of Microsoft's control over the operating-system platform.

Relevance to resilience

Microsoft demonstrates how control over a technological bottleneck can affect competition in adjacent markets.

The case supports the proposition that competition policy should consider whether conduct by a dominant platform makes the broader digital environment excessively dependent upon one technological gateway.

Principle

Control of an important platform layer can be used to restrict the development of competing ecosystem layers.

9. United States v. Google LLC — Search Distribution Case (2024)

The modern Google search litigation is highly relevant to ecosystem resilience.

Issue

The case concerned Google's distribution agreements and the mechanisms through which Google maintained default positions for general search.

Competition significance

Defaults matter because users may not actively search for alternatives.

A dominant position can therefore be reinforced through:

• default settings;
• distribution agreements;
• browser integration;
• device arrangements;
• ecosystem relationships.

Resilience principle

If competitors cannot obtain meaningful distribution, merely having technically available alternatives does not necessarily create effective competitive pressure.

The case illustrates the importance of distribution resilience.

10. European Commission v. Google (Shopping) — Case T-612/17

Facts

Google was found to have favoured its comparison-shopping service in search results over competing comparison-shopping services.

Decision

The General Court largely upheld the Commission's finding of abuse, while examining the precise competitive effects of Google's conduct.

Resilience relevance

Search is an important gateway to online commerce.

Self-preferencing can cause competing services to lose traffic and scale.

Once competitors lose scale:

less traffic → less commercial viability → fewer alternatives → greater ecosystem dependence

Principle

A platform controlling an important discovery gateway can affect the resilience of adjacent digital markets.

11. Google Android — Case T-604/18

Facts

The European Commission found that Google had imposed several contractual restrictions concerning Android, including arrangements relating to:

• pre-installation;
• search;
• browsers; and
• alternative Android operating systems.

Decision

The General Court substantially upheld the Commission's findings, while modifying the fine.

Resilience relevance

Android illustrates the relationship between:

operating-system control + application distribution + search + defaults

A dominant operating-system ecosystem can potentially reinforce its position across interconnected markets.

Principle

Competition authorities may need to examine an ecosystem across interconnected layers, rather than treating each digital service as completely isolated.

12. Apple — App Store / Epic Games Litigation

The disputes involving Apple's App Store rules provide another important example of ecosystem resilience.

Issue

Apple's control over iOS distribution gives it substantial control over:

• app distribution;
• payment mechanisms;
• developer access;
• platform rules.

Competition significance

Developers may depend on access to the platform's users while having limited alternatives to Apple's distribution infrastructure.

Resilience principle

An ecosystem can become fragile when one intermediary controls a critical gateway between suppliers and consumers.

Competition policy therefore examines whether platform governance prevents the emergence of alternative distribution channels.

13. Epic Games, Inc. v. Google LLC

Facts

Epic challenged Google's practices concerning Android app distribution and payments.

The case examined Google's relationships with developers, app stores and alternative distribution mechanisms.

Resilience relevance

The case demonstrates how control over app distribution and payment infrastructure can affect the availability of alternative ecosystems.

A resilient mobile ecosystem would ideally permit meaningful competitive alternatives in:

• app distribution;
• payment processing;
• discovery;
• developer access.

Principle

Competition can be weakened when technical architecture and contractual arrangements jointly make alternative distribution channels commercially ineffective.

14. Bronner v. Mediaprint (CJEU, 1998)

Although not a digital case, Bronner is important for understanding the limits of resilience-based intervention.

Facts

The case concerned access to a newspaper distribution system controlled by another undertaking.

Decision

The CJEU established a demanding standard for treating access to infrastructure as required under the essential-facilities doctrine.

Relevance to digital ecosystems

The case cautions that resilience cannot automatically mean:

"Every dominant platform must provide access to competitors."

Access obligations require rigorous analysis.

The infrastructure generally must be genuinely indispensable, and refusal must satisfy the relevant legal test.

Principle

Resilience supports competition policy but does not eliminate the demanding requirements governing compulsory access.

15. IMS Health GmbH & Co. KG v NDC Health GmbH (CJEU, 2004)

Facts

IMS Health controlled a pharmaceutical-sales database structure that competitors argued was indispensable for market participation.

Decision

The CJEU developed the conditions under which refusal to license intellectual property could constitute abuse.

Resilience relevance

The case is significant for modern digital markets because data structures and technical formats can function as competitive infrastructure.

Where an ecosystem controls an indispensable technical or data architecture, access may become relevant to maintaining effective competition.

Principle

Control over a critical information infrastructure can have consequences beyond the immediate product controlled by the undertaking.

16. Google Search (Shopping), Android and Microsoft: The Common Pattern

The cases can be viewed through a common ecosystem model:

This demonstrates why digital ecosystem analysis cannot always rely on conventional one-product market definitions.

17. Merger Control and Ecosystem Resilience

Resilience also matters before anticompetitive conduct occurs.

A merger may eliminate:

• an emerging competitor;
• an innovative technology;
• a potential ecosystem challenger;
• an important interoperability layer.

Consequently, authorities increasingly examine:

Existing competition

Who competes today?

Potential competition

Who could compete tomorrow?

Ecosystem competition

Who could become the next ecosystem challenger?

This is particularly important for acquisitions involving startups whose current revenues may be modest but whose technology or user base could challenge an incumbent.

18. Resilience and Digital Merger Assessment

A useful framework is:

Step 1 — Identify ecosystem bottlenecks

Determine whether one firm controls:

• identity;
• operating system;
• cloud;
• payments;
• search;
• marketplace;
• advertising;
• AI infrastructure.

Step 2 — Measure dependency

Ask:

• How many users depend upon it?
• How many businesses depend upon it?
• How costly is switching?
• Are alternatives commercially viable?

Step 3 — Examine network effects

Determine whether scale advantages make entry progressively harder.

Step 4 — Examine interoperability

Can competitors realistically connect to the ecosystem?

Step 5 — Examine multi-homing

Can users and businesses participate in multiple ecosystems simultaneously?

Step 6 — Assess foreclosure

Could the incumbent use one ecosystem layer to exclude rivals elsewhere?

Step 7 — Assess long-term contestability

Would intervention preserve meaningful future competition?

19. Resilience and Consumer Welfare

The resilience approach does not necessarily abandon consumer welfare.

Instead, it recognizes that consumer harm may arise through non-price dimensions.

Examples include:

• reduced privacy;
• reduced innovation;
• degraded interoperability;
• fewer choices;
• weaker service quality;
• increased switching costs;
• reduced technological diversity.

Thus:

Consumer welfare in digital ecosystems includes the ability to retain meaningful choice over time.

20. Resilience and Innovation

Digital markets often exhibit rapid technological change.

A highly concentrated ecosystem may reduce innovation by making innovators dependent upon the incumbent.

For example:

Startup innovation → incumbent platform dependency → acquisition or foreclosure → fewer independent challengers

Resilience policy seeks to ensure that technological innovation remains capable of generating new competitive ecosystems, rather than merely becoming another feature of the incumbent ecosystem.

21. Resilience and Interoperability Remedies

Competition authorities may consider remedies such as:

1. API access

Require access to technical interfaces under appropriate conditions.

2. Data portability

Permit users and businesses to transfer relevant data.

3. Interoperability

Require systems to communicate with competing services.

4. Non-discrimination

Prevent the platform from favouring its own downstream services.

5. Choice screens

Provide users with meaningful alternatives.

6. Separation remedies

In exceptional circumstances, separate structurally conflicting functions.

22. Risks of Using Resilience as a Competition Objective

There are important limitations.

A. Protection of inefficient firms

Authorities should not preserve competitors simply because they are competitors.

B. Reduced innovation

Excessive interoperability obligations can reduce incentives to invest.

C. Security concerns

Opening interfaces can increase cybersecurity risks.

D. Privacy conflicts

Data portability cannot override legitimate privacy protections.

E. Administrative complexity

Continuous ecosystem regulation may transform competition authorities into permanent technology regulators.

F. False resilience

Maintaining many nominal competitors does not necessarily create genuine competition.

The correct objective is therefore:

Effective competitive resilience, not competitor preservation.

23. Proposed Legal Test

Competition authorities could use a five-part resilience test.

Question 1 — Dependency

Is there substantial dependence upon a particular digital ecosystem?

Question 2 — Bottleneck

Does the undertaking control an infrastructure or gateway that competitors cannot realistically reproduce?

Question 3 — Foreclosure

Has the undertaking engaged in conduct capable of excluding or weakening alternatives?

Question 4 — Durability

Would the conduct make ecosystem dominance self-reinforcing over time?

Question 5 — Remedy

Would intervention restore contestability without unnecessarily damaging innovation, privacy or security?

Only where these elements are sufficiently demonstrated should resilience materially influence enforcement.

24. Digital Ecosystem Resilience as a Public-Policy Objective

Resilience can also serve as a bridge between conventional competition law and newer digital-market regulation.

Traditional model:

Price → output → consumer welfare

Digital ecosystem model:

Access → interoperability → switching → innovation → contestability → consumer welfare

This does not replace traditional competition principles. It supplements them for markets where architecture itself determines competitive possibilities.

25. Overall Legal Significance

The emerging significance of resilience can be summarized as follows:

1. Competition requires alternatives.
2. Alternatives require contestability.
3. Contestability requires realistic entry and switching.
4. Digital ecosystems can make switching prohibitively difficult.
5. Network effects can convert temporary advantages into durable dominance.
6. Interoperability and portability can preserve competitive alternatives.
7. Merger control can protect potential future challengers.
8. Abuse-of-dominance law can address ecosystem foreclosure.
9. Resilience must remain connected to competitive harm.
10. The objective is not to preserve every competitor, but to prevent irreversible ecosystem dependency.

26. Conclusion

Digital ecosystem resilience should increasingly be recognized as a legitimate dimension of competition policy, particularly in markets characterized by powerful network effects, high switching costs, data advantages, technological bottlenecks and ecosystem-wide integration.

The cases involving Microsoft, Google Search, Google Shopping, Google Android, Apple/Epic, Epic/Google, Bronner and IMS Health demonstrate different aspects of the underlying problem: control over a platform, distribution channel, data structure or technological gateway can affect competitive conditions beyond the immediate product concerned.

The strongest formulation is therefore:

Competition policy should preserve the capacity of digital markets to generate, sustain and transition between competing ecosystems.

Resilience is consequently best understood not as a free-standing mandate to preserve market diversity, but as a long-term contestability principle. Where concentration, exclusionary conduct or ecosystem integration makes competitive alternatives practically impossible, resilience becomes an important indicator that competition itself may be becoming structurally fragile.
