Linux’s 35th Anniversary and the Open Frontier
Members Newsletter – September 2026: Open Source is what it is because of the people who led us here, and keep us here. We all joined the community for different reasons, but many of us stayed because of the relationships and partnerships we built along the way, connections that run deeper than the code.

Open Weights Are Good. Open Source Is Better.
With openness in AI making headlines, we must educate policymakers, producers, and users of these technologies about what open-weight and Open Source AI mean for the four software freedoms: the freedom to use, study, modify, and share without the need to ask for permission from the rights holder.

Why Openness Matters More Than Ever
Members Newsletter – August 2026: Every model making headlines today, open or closed, sits on top of Open Source code, runs on Open Source infrastructure, and is based on openly shared research. That's not sentiment, it's just the history of how we got here. None of this exists without the Open Source community.

The AI Era Arcs Toward Openness
A surge of openness in AI has defined 2026. Amid calls for both caution and support, prevailing trends point to a future in which models are built and released openly. Recent research offers new insight into the adoption of open AI systems, who benefits, and the role of Open Source across the AI technology stack. The success of open-weight and Open Source AI reflects growing adoption, lower costs, narrowing performance gaps, and a desire for greater control over how AI is designed and implemented.

Openness Made All of This Possible
Every AI system in the headlines today, whether proprietary or Open Source, exists because researchers shared their work openly. That openly shared research produced Open Source software: the frameworks used to train these models, the libraries used to evaluate them, the operating systems, orchestration layers, and inference engines used to run them.

The strongest teams have learned the way: Open source needs more than code in play. It needs structures built to stay. And OSPOs provide that pathway. Because the best communities don't happen by chance. They grow when institutions choose to advance. OSPOs for Good. 🌍💚⚽ www.unopensource.org
The second half is underway. The conversations are finding their way. Across nations, languages, and cultures apart, Players are discovering a common heart. The biggest breakthroughs are rarely won alone. They emerge when communities build and OWN. UN Open Source Week. 🌍💚⚽ www.unopensource.org
