Software Freedom Conservancy: Give Up GitHub: The Time Has Come!

There are many good reasons to not host OSS projects on a fully closed source service like GitHub, but avoiding the risk of Copilot is a pretty weak one that will achieve nothing in practice. Regardless of where a project is officially hosted, by the very nature of being open source licensed, any person / organization can import the code to GitHub at any time they wish. IME, essentially any software package that has ever existed, has already been imported into GitHub by someone.

The debate over Copilot is important to have as the answer is not entirely clear either way. There is no practical way for any open source projects to avoid being imported into Copilot though, and moving project hosting makes no difference to this. Using Copilot as a justification for moving hosting service is at most a statement of unhappiness with their approach.
