You’re moving the goalposts. First you said they have the capability to unlock it and now you say they don’t.

The latest jailbreak for my phone is working for iOS 16.5.1

Older iPhones they have a vulnerability built into the hardware which is unpatchable (checkm8 bootrom exploit).

The source code for iOS has to be reverse engineered which takes some time so we don’t see jailbreaks for the latest phones on the latest iOS version anymore but they’re jailbroken eventually.

People are scouring over iOS and finding vulnerabilities but you still have this notion that nobody isn doing the same for Linux, even though it would be easier given that you can read the same code as the developers.
