I know a big sticking point for many people is that all code on GitHub feeds into CoPilot.
I don’t understand how this would help anyone who’s still stuck on GitHub for whatever reason to be able to escape GitHub. GitHub likely won’t support this. I guess it depends on why someone is ‘forced’ to use GitHub still. I’ve seen different reasons mentioned.
Ah, well, I don’t think there’s any officially hosted versions on GitLab. I guess it depends on why they chose GitHub, but maybe some attempts can be made to have them migrate if given enough reason that they agree with. So any clones on those other sites would need to pull in from GitHub on their own accord. And unfortunately any MRs into them would need to be replicated on GitHub which I’m assuming is the reason you ask and therefore likely won’t be happy with the answer.
