I had nothing against Windows 11 at first, but there is something I don't like about it now.
Do you know the File Explorer? After an update they made it so you can't move files by dragging them to the address bar or whatever (you still can by dragging to the quick access, another tab or window, whatever else there is, but not that specific way) and there was absolutely no reason I can think of that removing that would make for a better experience.
Aeons, I mean, eons ago, I used Firefox (when it didn't look like Chrome) until it was too much slower than Chrome on the same PC. Looking back I wonder if it was not long to go until it changed. Regardless, it seems like a no brainer to switch, at the time.
When I got a new PC, I wanted to switch back, but at that time, I had a mobile device (I already know what you said about those; Got curious to see the spam on YCM and I happened to look at this topic there). I used Chrome on there, I want to use the same browser on both PC and mobile (yes, there are other browsers I can do this with) and I just didn't want to switch my mobile browser. In the end, I stayed with Chrome.
TL;DR: I don't consider myself to have a valid reason not to switch, but I am fine with keeping things as they are.
