That's nonsense. Git is the best version control history of all time. It has some regrettable UX difficulties, but as far as the system itself, there is no better decentralized development tool.

There's a reason git came into existence for linux kernel development. The linux kernel is a project so massive and so decentralized that it needed a fitting tool to be able to tame the chaos. And git did that perfectly.

Out of curiosity though, what to you is a better source control system?
