People stick to what they are used to, and don't notice the enshittification. Windows users will happily tell you that Windows "just works", and that Linux is "too hard", because that's what they heard for years and never bothered trying for themselves.
Now, Linux overwhelmingly "just works", and using Windows is a constant fight with the OS. Instead of the problem Linux used to have where everything assumed you understood Unix already and new how to make good user decisions, Windows assumes you're a brainless moron and makes decisions for you without bothering to ask you or even tell you.
Even the fact that you have to install Linux scares people, because people are used to Windows coming on their computer, and in many cases don't even realize that Windows and the computer they are running it on are totally different things.
