After all, you don't even need Gitea for pure Git hosting. If you have a server with SSH access, just init a bare repo in a directory, push to that, and you're ready to go. No web UI needed.
The reason I'm still using GitHub is not code hosting. It's collaboration.
Used to do that years ago for my personal projects. Honestly does the trick.
If you don't want or need those things, bare git repos are fine and certainly easier to support (not that Gitea's that hard, though a few issues/PRs I've noticed have caused me more than a little concern about the overall quality of the project).
But for new open source projects of mine the ease of contribution and user expectation of a github repository are a trade-off worth making even so (I also maintain a self hosted master git repo that I consider the source of truth to -me- but these days it syncs from, rather than to, github, just because of the trade-offs involved).
