I may be wrong, but I think the point of this post is to show that all of these projects are losing a degree of portability by making the assumption that the `git` binary lives in `/usr/bin` on its target platform. There are many *nixes (like most BSDs, afaik) for which this assumption is incorrect.

EDIT: If that’s actually the goal here, though, I think this example doesn’t really make a solid argument. A ton of these results are from people’s personal dotfiles or from projects that have separate files for platforms that don’t keep `git` in `/usr/bin`.
