We all go through phases. I was on Cinnamon for the past six years and see myself returning to GNOME. I find myself wanting less cruft out of a DE as I get older. And more keyboard friendly too.

Also on Gnome for the minimalistic experience, but wobbly windows have a physicality that just clicks.

Somewhat ironically, now hosted on a Microsoft-owned closed platform.

Fortunately, Git itself is "open" and the source code can be migrated to another host without much difficulty. Migrating bug/issue tracking, PR management, and CI will be more difficult, but not impossible.

That said, I don't quite understand why no viable alternative has arisen.

Gitlab was a good attempt, but its interface turned out to be kind of clunky and more "team-oriented" than makes sense for general open source projects. I strongly believe that if it had a "slick" interface like Github, it'd be more popular.

Sourcehut is fantastic, but lacks the same "issues" and "pull requests" system.

Mailing lists honestly kind of suck, if only because there's zero semantic markup in email (excluding HTML-in-email which is a clusterfuck that nobody should use), making it difficult to track comment replies, embed code blocks, etc. And submitting patches over email is a chore compared to making a PR, viewing diffs, etc. on a platform like Github.

Also the social networking features of Github are unobtrusive and fun. Following other users has introduced me to a variety of interesting projects, starring projects is a fun way to show support, and the ability to watch a repo for releases is useful (although I wish it were an RSS feed instead).
