Windows 11 is only marginally worse than the baseline terrible set by 10. They screwed up the UI again and continued gradually ratcheting up Microsoft account requirements and new ads. If 11 hadn't have been released the later items would have just come to Windows 10 in the form of a feature update.

10 was full of spyware from the outset but for some reason people argue that it is better than 11 in this regard in a weird bit of revisionist history. The biggest problem with Windows 11 is it dumps hardware support for anything remotely old.

Personally, I think Windows 10 is the exception to this pattern. I don't think that it counts as a "good" release -- it just got rid of a couple of the more horrific aspects of 8. That said, I haven't been forced to use it yet, but it does look like Win 11 will be even worse than 10.
