I don't know if everyone is fine with Apple making so many changes. I think it's because they have no choice, being stuck with whatever Apple decides.
eg. for years you couldn't resize a window from the left edge and everybody was "fine" with it. When they actually bothered to implement it, it was astounding to think you couldn't do it before!
As for me, I await each Apple release with trepidation and fear.
Will my audio hardware continue to work? (They break the utilities most releases).
Will I need to buy a new version of Parallels or VMWare because Apple changed the virtualisation API? (This happened a few years ago).
Will my apps no longer work? (Goodbye useful 32 bit apps that I can't find a 64 bit version of).
Will they just break random things? eg. PDF viewing, Quickview of multiple files (both of these happened to me).
Will they change random things for the sake of it? eg. Giant spacing between icons on the menubar on Big Sur. Behaviour of the maximise button into "full screen" button just because they could (a few releases ago).
Will my machine be slower for no apparent reason? HFS+ to APFS makes my machine start up TWICE AS SLOW.
The best bits are due to the Objective-C message passing, old apps will make a "call" to a function that no longer exists and it won't break - it'll just do nothing. You literally have no idea if your app will continue to work between releases, even if it runs and the certificate for the app hasn't expired...
And I say this as a daily user of macos! It just isn't reliable between releases.
