Unfortunately just like the original post is anecdotal (I haven't had a machine fail to startup after an update since XP) not all anecdotes are born equal.
Interestingly, I don't see adverts myself, and I've never seen any at work. I -suspect- that's heavily regionalized.
Are there features I don't care for? Sure - I don't use OneDrive, I don't internet search from the Start bar, and I use Edge only occasionally. But it's not like somehow you -have- to use everything they ship.
I get it. An OS is personal. If you don't like Windows, use MacOS or Linux. All 3 have different approaches and one of them will fit you better than the others. Arguing over which is better or worse is like fighting over ice-cream flavors.
