I remember Sourceforge, bitbucket, and a host of other “source” servers. GitHub was nice for a while, but its just another iteration of the same. Heck a lot of the major repos (like Linux for example) only do mirrors to GitHub. The same with codeberg, Gitlab, and other centralized services.

At my last few jobs, we couldn’t host on GitHub because of HIPPAA compliance. It was fine. Self hosting git is VERY common in quite a few industries.
