Europe's Digital Sovereignty Crisis: Why Open Source Investment Isn't Enough

European organisations face a critical choice: maintain dependencies on US and Chinese technology platforms, or build genuine digital sovereignty through strategic infrastructure decisions.

The Open Source Paradox Threatening Europe's Technology Independence

Whilst the United States and China invest billions in open, scalable digital infrastructure, Europe finds itself dangerously exposed. Despite possessing 23% of the global open source developer talent pool—matching US contributions and doubling China's 12%—European organisations remain trapped in dependencies that undermine their sovereignty, security, and regulatory compliance.

Research from Harvard Business School reveals that firms would need to spend 3.5 times more on software without open source, representing $8.8 trillion in global demand-side value. Yet this foundation remains underfunded, fragmented, and overly reliant on non-European corporations whose platforms conflict with emerging European regulations including NIS2, DORA, and the Cyber Resilience Regulation.

Why Europe's Open Source Strength Doesn't Translate to Digital Sovereignty

Europe's open source contribution appears impressive on paper. Germany and France alone account for over 40% of European open source projects. However, this strength exists primarily at the developer level, whilst strategic control remains concentrated in US hyperscaler platforms subject to the CLOUD Act and Chinese state-directed infrastructure.

The fundamental problem isn't talent—it's architecture. European organisations have built critical systems on foundations they cannot control, creating dependencies that no amount of open source development can resolve without strategic migration to European sovereign infrastructure.

Three critical gaps prevent Europe from leveraging its open source advantage:

1. Infrastructure sovereignty gap: Open source code running on AWS, Azure, or Alibaba Cloud remains subject to extraterritorial jurisdiction, regardless of developer nationality.

2. Fragmented implementation: Member States contribute between 2-5% individually, lacking the coordinated industrial policy that drives US corporate investment and Chinese five-year planning.

3. Missing operational capability: European talent builds software, but organisations lack frameworks for assessing dependencies, designing sovereign architectures, and executing migrations from non-European platforms.

   
   

From Open Source to Operational Sovereignty

Recent EU initiatives including the Open Digital Ecosystems strategy consultation and Digital Commons European Digital Infrastructure Consortium (EDIC) demonstrate policy recognition. However, policy alone cannot bridge the gap between Europe's developer talent and operational sovereignty.

European organisations require practical capabilities that US and Chinese competitors already possess: systematic dependency assessment, architectural sovereignty design, and governed migration pathways to European infrastructure providers including OVHcloud, Scaleway, and IONOS.

The Compliance-Driven Imperative

NIS2, DORA, and CER regulations create legal obligations that US hyperscaler architectures cannot satisfy. Organisations face:

• Extraterritorial exposure: Data and workloads on US platforms remain accessible to US government requests under the CLOUD Act, creating direct NIS2 and DORA compliance risks.

• Supply chain concentration: Single-vendor dependencies on non-European providers violate resilience requirements across multiple regulatory frameworks.

• Governance gaps: Organisations lack visibility into dependencies, making risk assessment and compliance demonstration impossible.

European telecommunications providers, MVNOs, and regulated entities face particular pressure. Their network functions, customer data, and operational systems sit on platforms designed for US market priorities, not European regulatory requirements.

Where European Organisations Must Focus

Achieving digital sovereignty requires more than open source investment. It demands:

Dependency visibility: Comprehensive assessment across five sovereignty dimensions—jurisdictional control, data governance, operational autonomy, vendor independence, and security resilience.

Architectural redesign: Migration strategies that reduce lock-in whilst maintaining service continuity, leveraging European sovereign providers with GDPR-native operations.

Governance frameworks: Policies and controls that prevent future dependencies whilst ensuring compliance with NIS2, DORA, and sector-specific regulations.

European organisations need practical methodologies for moving from US hyperscaler dependencies to sovereign architectures—capabilities that policy initiatives and open source development alone cannot provide.

Building Europe's Sovereign Technology Future

Europe's 23% share of global open source talent represents enormous potential. However, realising this potential requires organisations to assess their current dependencies, understand their sovereignty gaps, and execute strategic migrations to European infrastructure.

The window for action is narrowing. US and Chinese platforms continue deepening their market positions whilst regulatory requirements tighten. European organisations that delay sovereignty assessments risk finding themselves locked into architectures that cannot satisfy compliance obligations.
