Windows 11 is far deeper into the sewer.
I don't know what school of contemporary design you hail from, but you can't piss on my back and tell me it's raining. Liquid Glass needs an 8.1 update, at the very least.
What you’re reacting to is aesthetic drift, not functional decay. Liquid Glass is a visual language experiment, not a UX rupture. You may dislike it, that’s fine, but equating it to Windows 8 is category error. One is a design iteration layered on top of a relatively stable interaction model, the other was a structural interface failure.
Also, invoking Media Player vs Groove Music as if those are meaningful historical markers of “user-hostile downgrade” is... generous to the point of fiction. Windows 8’s problem was input metaphors, not media apps.
This isn’t Apple becoming Microsoft. It’s Apple doing what Apple always does: overreaching aesthetically, then sanding it down in point releases until everyone forgets they were angry in the first place. Which, incidentally, is exactly what happened with Aqua, iOS 7, Big Sur, and every other supposed apocalypse.
I've been a Mac user for my entire life so maybe I didn't understand what things were like with Windows, but the fundamental problem identified by Howard, that there are many many system daemons and it is expected that the user not know what they are, or what they do, and to just leave them alone, has been the case for at least 20 years, I think.
Windows used to be known as the OS you'd "have to" tinker with.
Early versions of OS X allowed more freedom in what you could do with the OS. As soon as SSV/SIP entered, that cut off a lot of freeform access.
