Right, but that's the same sort of legalese excuse-making (or alternatively: just substitute imgur, which hosts most of that content).

It has nothing to do with whether or not /r/pics constitutes fair use, just if-it-isn't-fair-use-who-gets-sued? No one, at the time or now, seriously thought that there was a legal problem for anyone with reddit. So why pinterest? Again, part of me is really suspicious that it's because it's a chick site that doesn't cater to geeks.
