I would guess (and probably get downvoted for this) that it's because GIT is so widely used, is not well structured and overall group source control is not well understood by developers. If you are exposed to several source control systems, you would avoid GIT, at least until you know what you are doing. But so many people use it and don't understand what they are doing, there are massive numbers of conversations just like this article - often between people who have never used anything other than GIT.
