They haven't pulled the plug on github yet, but my understanding is that Gentoo intends to drop it long term. In general, I would expect any of the projects that leave GH because they want to avoid being used to train AI would avoid leaving even a mirror behind (since that would defeat the point). (This is not intended as a value judgement, just saying that there exist projects that are doing this)

Thanks, noted at https://github.com/osendowment/endowment.dev/issues/34#issue...
