On the side of the Open Source ecosystem

Members Newsletter – June 2025

May was a full immersion into some of the largest components of the Open Source ecosystem, from maintainers to founders. Jordan Maris (OSI EU policy manager) and I went to the Open Source Founders Summit in Paris to meet small businesses, mature companies and startups and share our knowledge of the Cyber Resilience Act. It turns out we were also there to learn as we noticed a couple important misunderstandings of the OSI.

We noticed how much opportunity there is to promote OSI’s policy program. It hit me how few people knew that OSI grew the policy team by four people, hired to do the important work of protecting the ecosystem.

We also realized there is a belief amongst many that OSI defends the interests of the large tech organizations, a false image we don’t want to own. That is not what we are trying to do. OSI maintains the Open Source Definition, the foundation for the whole ecosystem, not just big tech. Our vision is to help “build a world where the freedoms and opportunities of Open Source software can be enjoyed by all.”

I made it a point to start a conversation with the OSI board to better understand where this misunderstanding is coming from and how we might repair it. Watch this space for more initiatives toward that end in the near future.

Executive Director, OSI 

I hold weekly office hours on Fridays with OSI members: book time if you want to chat about OSI’s activities, if you want to volunteer or have suggestions.

How the World Is Celebrating Open Source Maintainer Month

Article from The New Stack

For their contribution to Maintainer Month, the OSI has collected nearly four dozen stories from maintainers to create a moment of visibility, publishing them all as a curated collection at OpenSource.org

Celebrating Maintainer Month

50 maintainers came together for Maintainer Month to share their stories. These maintainers not only write code, review issues, and merge pull requests—they also navigate community dynamics, mentor new contributors, and increasingly adopt security best practices to protect their code and users. They literally keep the digital infrastructure up and running for the benefit of all. Read their stories.
