In September and October 2025, RubyGems and Bundler, the clients and package registry for the Ruby language, had most of their maintainers removed by RubyCentral, the non-profit foundation that claimed ownership of these repositories. Since then, some of these repositories have been moved into the Ruby organisation and some of the ex-RubyGems maintainers have created an alternative hosting service, gem.coop.

I was a neutral party involved with initial mediation between RubyCentral and the maintainers before and during this transition and helped gem.coop bootstrap a governance process.

These events have much for non-Ruby projects to learn about non-profits, governance, money and access in open-source and I will share my learnings without taking any particular side in the disputes.
