There are plenty of alternatives for git hosting. The last thing which needs to be migrated before we get an exodus off this vibe coded monstrosity is reputation (i.e. github stars) which are inherently sticky.

I like Fossil, but there are good reasons to use git too.

There are many git hosting options, including some for self hosting. its a lot easier to switch to a different version control host than to a different version control system.

We had Launchpad before Github (IIRC).

> Luckily we already have a distributed version control system that can take over github

Surprised that this wasn't just a link to Git. The biggest benefit of Git over predecessors was that it enabled decentralization. Github re-centralized the common case for the sake of convenience.
