GitHub is a company & git is a core technology which is replacing Subversion for version control. FWIW, WebKit could have moved to Gitlab, Gitea or Bitbucket & still used git. Subversion & CVS's days are numbered - the writing was on the wall for many years
They kept the bugzilla tracker and will probably not use any CI on GitHub meaning migrating out will be easy, so not much to worry really. Problem is when repos rely on GH issues, projects, actions, codespaces, etc. because then migrating out becomes an enormous task.
Subversion started in that phase so maybe they're just trying to delay the inevitable.
What do you mean? (Not facetious, I'm out of the loop on such matters - I thought it was still just git on the cli?)
I assumed it to mean, what with GH being owned by Microsoft, it’s now in the extinguish phase of EEE (embrace, extend, extinguish). Though if anything I think it’s in the extend phase.
