To me, the Tumblr is pointing out an overall lack of attention to detail. Some of these obvious bugs should have never made it past QA/testing, but somehow they did - and that's sloppy UI, regardless of whether it was an intentional "do that" directive.

I understand what you're saying, and perhaps the name of the Tumblr should change to "Issues with iOS7", but that sounds pretty boring to me. Instead, we can all agree that sloppy/bad decision-making, sloppy QA practices, etcetera can be learned from, and that there is value in identifying (and avoiding) these mistakes both in the works of others and in our own work.
