What "walled garden"? The Mac-only apps aside, what's that that you couldn't get on Windows (and most even on Linux), either the same thing, or a zero-switch-cost subscription (it's not like you need to rebuy something to go from Music to Spotify for exampe).
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.
