Was there ever a time when this was not true? M$ was always among top hated companies since 90s, arrogance, fuck-U to users all around, absolutely ignoring any standards larger than them, and famous 'Embrace, extend, and extinguish' which was pathetic to watch for any engineer worth 2 cents.

Top notch user experience peak was Windows XP and every subsequent release was massively larger, clunkier and slower while requiring way more resources, was spying on the users more and more. Office has similar story, peak of usability was maybe 2007 with ribbon introduction (which still a lot of power users hated with passion since it was far from clean design, more seemingly designed by committee of marketing guys).
