That may be true. But the fact here is that UI always become more illegible and that's why people are hating this update. It needs much more load on brain nowadays to click a button as everything looks so flat. Just for the sake of new update and job security by designers. We just get used to it later with the flatness and then they make it more flat. The cycle continues.
