Celebrating Generosity and Growth in the OSI Community
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.
Open Source Without Borders: Reflections from COSCon’25
Witnessing China’s Deepseek moment firsthand and learning about Kaiyuanshe’s dedication for over a decade building and championing China’s Open Source community with such vision and commitment is truly inspiring.
DPGA’s Annual Members Meeting: Advancing Open Source & DPGs for the Public Good
The DPGA’s Annual Members Meeting highlighted several priorities that resonate strongly with OSI’s mission, including promoting Open Source software, advancing public-interest AI, and strengthening global collaboration.
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.
OFA Symposium 2025 and the Launch of the Open Technology Research Network (OTRN)
The OpenForum Academy Symposium 2025 organized by OpenForum Europe (OFE) brought together researchers, policymakers, practitioners, and open technology leaders for two days of deep inquiry into how open technologies shape our economies, infrastructures, and societies.
Open Source: A global commons to enable digital sovereignty
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?
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.
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.
