That makes the decision to not use Codeberg even easier for many. If you are after a sustainable and stable code repository to host your projects then Codeberg disqualified themselves. It goes down regularly as much as GitHub and loses to GitHub on discovery. Now, you can potentially lose your entire account and projects by posting a repo that can have AI with auto-complete. If Linus Torvalds (pro-AI) published his scuba-diving software [0] there, which there is a CLAUDE.md file in the repository, it would get banned. [0] https://github.com/subsurface/subsurface
