This definitely does not extend to games. I remember microsoft games having terrible UX over a decade ago (not the game, the account garbage around it).
So, I've had a pretty shit time with Microsoft products over the last ten years, but it wasn't quite as bad 5-7 years ago. Our disagreement on that might be that I'm only in my late 20s, so if you're older than I am, or had newer consoles than I had around that time, I might be a little more tolerant of jank.
But according to the other replies, it seems Microsoft has been purging QA for years now.
