This generic statements can be said about basically any technology (MS MFC anybody? (L)DAP? IBM Websphere studio J2EE abominations?) if you are smart enough / have enough time to dig around. It doesn't help discussion at all (and plenty of folks complain about git all the time), since one can't avoid being branded as lazy/stupid if its not grokking this uber important yet trivial tool like me (TM).

But then there is Mercurial, used it decade and a half ago and it contained literally everything good about distributed model I could ever wish for, with maybe 50% of Git's complexity. Yet cargo-culting gonna cargo-cult, if Linus uses it so must we since we are not subpar and the rest be damned.

Yes sure its the tool to stay, and eventually can be learned well. But its design is far, very far from the most important software design principle (KISS).
