Bzr is a great counter example.

Bzr "lost" because git had GitHub, whereas Launchpad was one too many things and slow to optimize for modern sensibilities.

(And Linux used a different VCS before git, so that didn't matter in adoption)

Imagine a world without GitHub, and I don't think git would be our go-to VCS. Though maybe not even Baazaar, but there are things like Mercurial too.
