Im also not sure they can call it a USBC port if its not operable with other USBC accessories, that would depend on the USBC standards body.
The USB-C specifically allows for custom implementations using some of the pins.
I just don’t get it. What’s the point of limiting when it’s been out for years on the iPad just fine? Is Apple trying to make this an exclusive feature?
I can see it if they wanted to ensure cables work properly for high speed data transfer; something missing from iPads. Alternatively, it could be part of a security implementation to limit access to iPhone data or protect form electrical faults from non-certified cables; a move that might make sense given iPhones are much more likely going to be charged in public locations; possibly with cables and power sources of unknown origin.
I don't understand why Apple would add an MFi chip to USB-C. They didn't do it when the 2018 iPad Pro came out, and they certainly didn't do it for the 10th-generation iPad, so why do it now, and only for the regular iPhones?
As I pointed out above, there could be a number of legitimate reasons.
Apple sticking it to the world or the EU?
Certainly not the EU since it would fully comply with the regulation.
