The eu case seemed to make more sense and was pro consumer: open up messaging / App Store and switch to usb c.

This one seems different at first glance,

Nah, users really are dumb and really will follow steps that will result in malware getting on their devices. This happens all of the time in Android-land. Burying the setting won’t change this, people will follow tutorials to disable the security protections if they think it will get them the content they want (and, in some cases, it will, wrt pirate apps etc).

There’s no real way to square the circle: either Apple (and the state) has realtime app censorship control (nominally for malware, as well as any other thing the state or Apple’s business model feels existentially threatened by), or the user can install any app they want, with all of the associated risks. Even with notarization and self-distribution you’re still in the first category because the state can compel Apple to treat protest apps or non-backdoored e2ee messaging apps the exact same as they do malware, and prevent them from launching.

Users mostly want the former, because most users aren’t worried about government censorship or oppression. Tech people and cypherpunks and pirates and protesters usually want the latter. Tech people usually want the former for their parents/grandparents for whom they serve as device sysadmin.
