>People very rarely switch phone operating systems.

This is true and I'm not claiming that switching is a common occurrence.

That said, the more likely os migration is from iOS-to-Android rather than Android-to-iOS. I know more than a dozen people that have switched from iPhone to Android. I know nobody that switched from Android to iPhone.

Of the people that want to leave iOS for Android but haven't pulled the trigger... what's holding them back is the Apple Watch and the iPad. The Android ecosystem (Samsung) doesn't have competitive hardware in those areas.

My friend really wants to switch to Android for the superior Google AI Assistant but can't because her Apple Watch tracks her medical stats better than Samsung/Garmin watches. She already uses Google-everything-else with Google Sheets/Docs/Calendar/Keep/Gmail/Voice. If Tim Cook made Apple Watch work perfectly with Android phones, he'd lose her as a customer.

>Why doesn't Apple not let you have a MacBook unless you have an iPhone?

PowerBook and MacBook were around as standalone before iPhone existed. The Apple Watch was always created & marketed as an accessory for the iPhone. The AirPods is a hybrid situation where they partially work with Android but it is crippled with missing features. You have to use AirPods with Apple's ecosystem for full functionality.
