Yeah I understood what op is looking for. Having your code hosted on GitHub was what I was referring to with hosting, not your platform itself (we are talking about selfhosted stuff here anyways).

The devs need to move off GitHub? No shit? Maybe, as a user, preferring projects that host their code elsewhere could be an incentive to devs using something else then? Like, looking for a selfhosted audio project and asking if there’s any that doesn’t primarily rely on GH?

It’s not that it’s totally absurd being somewhere else. The whole KDE project has it’s own Gitlab and many projects are on Codeberg or their own forges. Yes, the overwhelming majority is on GitHub. That doesn’t mean looking for projects that aren’t is dumb.
