The fact of the matter is, 99.9% of people who buy a Mac are not going to know what subpixel hinting is. Or care too much that they can't delete Chess.app. To them, the Mac is nicer looking and easier to use than ever.
Will iOS devs care? Not at all - developing for the Mac has become easier with Catalyst. It's easy and cheap to get a new audience for your apps. Will web devs care? Not while homebrew and all of the packages in it still work fine. I, as a web dev, have everything working great on the Big Sur beta already.
And as for some saying that MacOS is becoming more iOS like: Yes, it's been happening since Mac OS X Lion with the fullscreen Launchpad. Nothing has changed.
