Locked down devices. Then making more money from selling subscriptions, developer certificates, running "app stores", advertising services, etc.

To get the full functionality from the device, it is difficult to avoid obtaining an "AppleID". There is an "incentive" for users to sacrifice privacy and control to Apple. That appears to be intentional. Then the after purchase data collection and storage begins.

I am glad these practices have not spread across the entire hardware industry. Imagine buying an SBC and being asked to purchase an "RPi Developer Certificate" or register a "SiFiveID".
