This happened on my work machine. One day I noticed tons of important files had been deleted without my permission after being migrated to OneDrive online only. At no point did I authorize anything like this and it took some time to copy them all back and disable everything I could access related to this.

Utter insanity that this can happen in a major OS. I switched to Linux for personal use years ago and have only gotten more grateful for that decision over time. My head would explode if a Linux distro tried any number of things that Windows regularly does to abuse their users, it's unfathomable.
