If you google «git download» or «install git», that’s what you get. There’s also no package manager or 3rd party packages to worry about or learn how to use. That’s my gut feel, at least.

Git bash is based on some ancient cygwin version. You can see that e.g. the «cygpath» utility is still there. MinGW/Msys forked from cygwin due to some techno-political disagreement that I can’t be bothered to learn more about.
