You can't seriously compare how inappropriate Windows 8 was on desktop to the latest macOS. Bad UI aside, the OS is effectively the same OS X from 2001 with some fresh skin.
Also a lot of people hate on macOS changes, I myself did not upgrade to the latest version.
I guarantee that there is enough stuff from 2001 that won't work in Tahoe.
I'm still on Sequoia on both my Macs. I updated my iPad Pro to iOS 26, decided it was meh, and am not updating my phone. My iPhone is over 4 years old and figure the new iOS will run like crap on it and then I'll be forced to get a new phone.
Actually, I think Tohoe is much worse!
Windows 8 is fundamentally just Windows 7 with a full screen start menu. This is a dumb usability downgrade, but unless you went out of your way to install Metro apps, it wasn't such a big change. Your apps worked the same way they always had.
