Both iPhones and MacBooks (to a lesser extent) rely on US services provided by Apple. They (techically) can execute arbitrary code on your devices if you have auto-update enabled (and probably even if not). They’re almost definitely spying on you, your habits, your decisions etc.
Good for you!

I mean once you switch off from key things like email, calendar, and cloud storage, then it’s a lot easier to move over to a different device.
