I completely agree. I don't see why some developers need to solely depend on GitHub for private use when you can self-host GitLab/cgit with a cheap computer to host your projects. Open-source development has already thrived without the likes of GitHub even before it was founded.

Perhaps the time to self-host your projects just like how Mastodon allows self-hosting an instance is more important than ever, which will probably be better for open-source instead of centralizing and increasing our dependency on GitHub.
