This is certainly not an excuse for the clearly bad UI design the article describes for iOS, but unfortunately Apple is not the only one afflicted with that disease. The situation on Android is not exactly rosy either.

I get particularly aware of the serious UI problems when trying to use GPS navigation (waze, here, google maps) in a car. Buttons with various colours, contours and sizes, non-intuitive interactions where one has to swipe starting from various confined areas, annoying dialogs or confirmation screens appearing one after the other, sometimes even spontaneously. There is not even a modicum of consistency regarding the most basic elements, e.g. a yes-no question or a dismissible message.

I hate to say it, but the first iOS of 2016 was (and probably remains) a champion of elegant and consistent UI design. Today, it's almost as if the iOS and Android ecosystems are competing for who has the most unintuitive and confusing UI.
