Well, git should not be the default, but that doesn't make it a bad tool. Think about different heads for screw drivers. Just because you have bought a set and there is one you never or seldom use, doesn't mean it's a bad head. The moment someone has a screw which needs that head suddenly all other heads are useless and that's the best head you can have. Right?

(I'm not so sure what the right English word for "head" is, I hope it still makes sense even if I use the wrong one)

Or another example. Cars are a highly specialised tools. Nobody is allowed to use one if they haven't shown that they have learned to use it properly via standardized exams. Maybe if a company uses a lot of git the mistake is that they don't require people to learn it properly first, either by offering courses or by filtering in the hiring process.

And since I've spent month learning it and now can use it even in potentially destructive situations like "git rebase -i" I can tell you that for me it's way more useful than SVN or CVS ever were.
