The USB transfer speed claim is misleading to say the least. The iPhone 15 was already capable of up to 10Gbps transfer speed (USB 3.0 support). You could quibble over the fact that the included cable didn’t support that (if only the USB-IF could get its shit together), but to claim the hardware doesn’t support it is a lie.
Also, non-US iPhones support both physical SIM and eSIM.
No fictional dystopia needed. China already performs mass surveillance and has systems in place to enforce desirable behaviours in citizens. This is just another evolutionary phase.
