The Open Source community has spent two decades building the scaffolding to make patent threats rare and containable. Developers who understand that landscape can focus on what they do best: innovating in the open, confident that the legal ground beneath them is far more stable than any patent myths suggest.

The top 20 OSI-Approved licenses most frequently sought out by our community in 2025 based on number of pageviews.

Members Newsletter – December 2025 As we reach the final weeks of the year, I find myself reflecting on a season that invites both gratitude and giving, two values that feel especially resonant for our community. Serving as Interim Executive Director these past months has only deepened my appreciation for the people who make Open Source possible.

In a world increasingly run by software, countries around the world are waking up to their dependency on foreign services and products. Geopolitical shifts drive digital sovereignty to the top of the political agenda in Europe and other regions. How can we ensure that regulations protecting our citizens actually apply? How do we guarantee continuity of operations in a potentially fragmenting world? How do we ensure access to critical services is not held hostage in future international trade negotiations?

Europe is at a crossroads. The Summit on European Digital Sovereignty marks an important milestone for the EU and its member states in aligning on a shared strategy for achieving real and lasting European digital sovereignty. As the EU pursues the goal of digital sovereignty, we urge you to harness open source — that is, technology that is free to use, inspect, adapt, and share — as a key enabler of this strategy.

Open source is suffering from its own success. The ecosystem that once thrived on volunteer energy now faces existential questions: How do we sustain the infrastructure that powers the modern world? The answer isn’t just money—it’s people, governance, and collaboration.

The next 25 years depend on what we do together now.
