A github server is much easier to set up than a subversion server. The reason people use github is because it's free, and because it has issue tracking and a wiki and forking which plain git knows nothing about.
And in general I feel that their gh cli tool doesn’t get enough praise. Being able to do easy API calls and queries for use in shell scripts (or just the terminal) is great, and the gh copilot is occasionally useful as a refresher for command syntax, or for deciphering some oddball git command you found online.
It’s a massive beast to tackle, and few people have a reason to. I don’t see anything doing what git does having a chance at competing with it. It requires a paradigm shift and a completely new product/approach to versioning to break the git dominance.
You can't set up a GitHub server.

Although...you can set up a Github on-prem server -- or at least this used to be true. Talk to Github Sales and be prepared to write a check.
Oh here we go again. You are wrong my friend. Firing up a basic SVN server is a matter of minutes. You just need to run several simple commands.
