I spent a year making my company's iOS apps accessible (meaning usable for the blind and people with vision disabilities). I had to do a lot of weird shit either because of bugs in Apple's VoiceOver technology or because of the strange way in which our code base was broken up into modules (some of which I did not have access to) and I would always put in comments explaining why I was doing what I was doing. The guy doing code review and merges would always just remove my comments (without any other changes) because he felt that not only were comments unnecessary but also they were a "code smell" indicating professional incompetence. I feel sorry for whoever had to deal with that stuff at a later point.
