Windows becoming completely hostile towards power users.

I used to LOVE Windows, I even made fun of friends who were using Linux, which I only used on servers because I thought the desktop experience was sub par (and at the time it was, we're talking 10-15 years ago). Then Windows 8 came and I stayed on 7 because the experience was bad. Then 10 came and data collection started getting out of control, so I had to jump through a bunch of hoops just to make it usable and "private enough". Eventually things got so bad around 2019 that I realized that I was spending more time fixing that pile of crap than the average Arch user and I decided to give Linux a serious try.

I was somewhat annoyed by some UI/UX flaws but eventually I got used to it, and with the coming of Linux gaming I started using Windows less and less (it's an AMD system so the Linux experience is excellent), eventually last year I realized that I hadn't booted it in months so I just wiped that drive and started using it for games. I've also gotten a lot more paranoid about privacy and sandboxing proprietary software.

Now with Windows 11 things have gotten so bad that even my students are making fun of it so I don't think I'll be coming back.
