Just migrate to Forgejo/Codeberg[1][2] or SourceHut[3]. Both are like a light speed compared to GitHub and GitLab.
Sourcehut is basically a really barebones web interface for git server, so I don't think it's really comparable to GitHub
For hosting your own projects that's sometimes not a viable solution either. Limiting your open source project to platform other than GitHub hurts it's discoverability, because usually GitHub is what most devs and non devs associate with open source. I heard a lot of "It's not open source if it's not on GitHub". You can mirror your project to GH of course
"Just migrate to X because it's faster" doesn't work that well in the real world
Pushes and pulls would still kinda work, actions not so much (but that's cause it needed to transfer more then 100MB)
