I am someone that also left GitHub. [1] To the author, yes, it's worth it. I didn't go to another service, though; I set up Gitea on my own server. Because of drama there, I'm going to have to replace Gitea as well. But GitLab itself is going down the drain, I'm not welcome on SourceHut, and I haven't heard the best things about Codeberg. Also, git needs a replacement. [1]: https://gavinhoward.com/2020/04/i-am-moving…
(I'm not a bit willing to put my code on the likes of SourceHut or Codeberg. They are just new iterations on the Sourceforge/GitHub pattern that didn't go bad up to now. Besides, I like to keep the software I don't publish on my computers.)
