As far as I can tell this basically means that all apps must be approved by Apple to follow their “platform policies for security and privacy” even if publishing on a third party app store. They will also disable updating apps from third party app stores if you stay outside the EU for too long (even if you are a citizen of an EU country, with an Apple account set to the EU region).
The idea that preventing app updates is in line with their claims of protecting security is utterly absurd. “Never attibute to malice what can be explained with stupidity,” but Apple isn’t stupid.
Apple users will accept anything Apple does to them. In their eyes, Apple can do no wrong. They will defend this all the mental hoops they have available.
I’d like to see Apple hurt, but somehow, I want to see its users hurt even more. They willingly buy these products and even defend them. Things should just get so bad that even the most devout Apple user questions Apple. No idea how bad it has to get, but I’d be very curious to find out.
