It's easy to forget nowadays but OpenBSD was ahead of the pack in providing anonymous CVS access at a time when getting the source meant only getting tars of the source for a release.

git is GPL, which BSD people tend not to like.

I think they're writing a git replacement under the BSD License, though I don't know how progress is going on that.

The author of the BSD version, Game of Trees (got), recently did a presentation at EuroBSDCon, and that video is online[1]. It focuses on security and has quite a bit of functionality, including some new things like having multiple working directories from the same repository and even checking out subdirectories from the repository. Looks like progress is going well. It doesn't do network/remote actions, but you can use the normal git binary for pushing and pulling.

> having multiple working directories from the same repository

  $ git worktree add ../foo-develop develop

This comes up every year on misc@, so allow me to just link you to a thread about it: https://marc.info/?t=156380787000001&r=1&w=2

tl;dr, it's the devil they know and they need no feature that Git or Mercurial provides.
