I would (grudgingly) accept this argument for iOS, but for Mac OS it doesn't make any sense.
iCloud? You can use Google Drive or Dropbox or whatever MS calls theirs. Apple Music? Pretty sure it plays at both.
Most major apps are cross platform (Adobe, Microsoft and such), or Electron based.
Syncing with your iPhone? You can do that from Windows and Linux as well. Airpods? Work with Android and Windows too.
And so on.
I mean Average Joes off the street, who can't find Ukraine on the map, not HN users of Macs with a SaaS side hustle.
You didn't read what I said. I said MacOS IS a monopoly in the Apple ecosystem.
Apple users dissatisfied with how MacOS is changing, as the one I was replying to, have nothing else to switch to without uprooting themselves out of the Apple ecosystem altogether, which most don't do but just put up with it.
