Well, I guess. It's not a surprise LinkedIn and GitHub are owned by the same entity. Both are degrading down to the same Zuckernet-style engagement hacking, and pseudo-resume self-boosting portfolio-ware. If the value of open source has become "it gets me hired", then ... fine. But that's not why many of us do free software development.
GitHub's evolution as a good open source hosting platform stalled many years ago. Its advantages are its social network effects, not as technical infrastructure.
But from a technology and UX POV it's got growing issues because of this emphasis, and that's why the Zig people have moved, from what I can see.
I moved my projects (https://codeberg.org/timbran/) recently and have been so far impressed enough. Beyond ideological alignment (free software, distaste for Microsoft, want to get my stuff off US infrastructure [elbows up], etc.) the two chief advantages are that I could create my own "organization" without shelling over cash, and run my own actions with my own machines.
And since moving I haven't noticed any drop in engagement or new people noticing the project since moving. GitHub "stars" are a shite way of measuring project success.
Forgejo that's behind Codeberg is similar enough to GitHub that most people will barely notice anyways.
I'm personally not a fan of the code review tools in any of them (GitLab, Foregejo, or GitHub) because they don't support proper tracking of review commits like e.g. Gerritt does but oh well. At least Foregejo / Codeberg are open to community contribution.
