BRUSSELS — Europe has declared digital sovereignty its defining mission. The European Commission rolled out its Technological Sovereignty Package in June. That package binds together Chips Act 2.0, the Cloud and AI Development Act, an energy roadmap and a detailed EU Open Source Strategy. Officials see open source not as a cost-saving tactic but as the practical instrument to cut dependence on non-European suppliers.

Yet fresh data from this week’s Open Source Summit Europe in Prague delivers a sharp warning. European developers pour code into global projects. They account for nearly 40% of contributions to foundational systems such as Kubernetes and OpenStack. Their share climbs above 44% in the Linux kernel. Governance participation tells another story. Only 37% of European organizations contribute to project governance. That effort represents just 15% of total governance work, according to the Linux Foundation’s 2026 State of Open Source in Europe report.

Thierry Carrez, general manager of Linux Foundation Europe, captured the gap in an interview at the summit. “Europe is not necessarily strategically investing in the governance of those open ecosystems, and so from the outside if you look at those ecosystems, they are going to be dominated by companies from the US and from China.” The message lands with force. Writing code alone does not equal control.

The numbers still impress. Ninety-four percent of European organizations now list digital sovereignty as strategically important. Sixty-one percent call it very important. Organizations that maintain advanced open source governance programs report returns exceeding four times their investment. Those without formal governance average 3.6 times. The gap shows up in daily operations. Sixty-three percent have boosted spending on dependency management to meet regulatory demands. Forty-eight percent keep private forks of open source projects.

The Strategy Takes Shape

Brussels responded with concrete steps. The EU Open Source Strategy, released as part of the June package, sets four objectives. It pushes deployment of open source alternatives that match European rules and values. It scales the Open Internet Stack into a central catalog of approved building blocks. It backs business accelerators that offer mentoring, legal advice and market support to European open source companies. And it commits to stronger governance across public and private efforts.

Commission estimates call for roughly €2 billion in combined public and private spending over seven years. That money targets public procurement reform, integration with Horizon Europe research, and coordination with member states via the Digital Commons European Digital Infrastructure Consortium, known as EDIC. Officials want 30 million active users of open source collaboration tools by 2030. They also embed open source requirements in the EU Digital Identity Wallet and promote its role in meeting the Cyber Resilience Act and NIS2 directives.

But adoption brings new headaches. Ninety-four percent of organizations use or test generative AI coding tools. Those tools flood maintainers with bug reports and pull requests. Many projects already strain under the load. Private forks offer short-term escape. They do not solve the deeper question of who steers the direction of the software Europe relies upon every day.

And the reliance runs deep. The Commission acknowledges that the EU spends €264 billion annually on IT products and services. Most of that money flows to proprietary solutions from non-European vendors. The resulting lock-in undermines strategic autonomy. Open source offers an exit. It supplies auditability, the ability to modify code and freedom from single-supplier risk. Security follows. Supply-chain integrity sits at the intersection of the Cyber Resilience Act, DORA and the broader sovereignty agenda.

At the Prague summit, Linux Foundation experts Madalin Neag and Mirko Boehm argued that these initiatives converge on one goal. They aim to secure the software supply chains that support Europe’s economy. Without visibility and control, sovereignty remains talk.

Member states move at different speeds. France, Germany and the Netherlands lead in public-sector adoption. Poland recently added open source targets to its digital strategy. Sweden updated national guidelines to align with EU policy. The Netherlands now prioritizes open source in municipal procurement. These actions build momentum. They also expose uneven capacity. Not every government maintains the expertise to review code or participate in upstream projects.

Carrez and others urge a shift from consumption to contribution. “The open source allows organizations to reduce their dependence on a particular vendor or country, but simply using open source software is not enough to guarantee effective control over the technology,” he said in the Linux Foundation release. “By contributing upstream and participating in open governance, European organizations can gain greater autonomy while effectively drawing on the global open source technology heritage.”

Industry voices echo the call. Over 500 for-profit open source companies already operate in Europe across cloud, cybersecurity, industrial systems and data. Their success depends on talent, funding and policy consistency. The sovereignty package promises open source business accelerators and eligibility for the European Competitiveness Fund. Whether that translates into sustained European leadership in project direction remains the test ahead.

Security adds urgency. Recent years exposed supply-chain attacks and foreign influence risks. Regulators responded with mandates for transparency and accountability. Open source meets those demands when properly governed. It fails when treated as free labor. The report highlights that advanced governance correlates with higher returns and lower risk. Organizations ignore that link at their peril.

So the next phase begins. Europe must turn its code contributions into governance seats. It must fund maintenance of critical components. It must train public servants and corporate teams to review, contribute and lead. The €2 billion commitment buys time. Results will depend on execution over the next seven years.

Recent coverage from the summit reinforces the stakes. Diginomica’s report from Prague notes that the meaning of sovereignty has shifted. It no longer stops at choosing open source over proprietary tools. True sovereignty demands understanding the software and shaping its future. The Stack’s coverage adds that switching to open source alone will not free European companies from outside influence. Participation, early and often, remains essential.

The original analysis that framed much of this discussion appears in TechRadar’s October 8 article. It traces how open source already underpins cloud, finance, government and AI across the continent. The new strategy seeks to convert that usage into strategic advantage.

Europe possesses the developers. It now builds the policy scaffolding and funding mechanisms. Success will show in who holds the seats at project governance tables five years from now. The bet is placed. The work starts today.
