I don't think they are 'stupid'. I think in general the overall look and feel of applications, websites, etc is all very subjective. For example I really strongly dislike many aspects of Material Design even though most people seem to love it.

Also since they are constantly changing and tweaking things I've given up on constantly criticizing looks (or trying to customize things to suit my taste) and I just focus on usability and functionality. I only get upset when a user interface has become so poor that the former things suffer as a result.
