Patents and Open Source: Understanding the Risks and Available Solutions
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.

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.  https://opensource.org/blog/open-letter-harnessing-open-source-ai-to-advance-digital-sovereignty
Open letter: Harnessing open source AI to advance digital sovereignty
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?
Sustaining Open Source: The Next 25 Years Depend on What We Do Together Now
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. We need companies to invest not only funds but also employee time, foundations to work together instead of in silos, and communities to plan for the full lifecycle of projects. The next 25 years depend on what we do together now.
