Any argument in this vein must also apply to the Mac. The hardware is mostly the same. The OS is mostly the same. The native apps and services are identical, as is the security story. So why should the Mac not be locked down if the iPhone is? Put another way, what prevents Apple from using the exact same reasoning to lock down my Mac in the future, perhaps under pressure from authoritarian governments? After all, the technology (notarization) is already in place and is actively being abused for iOS app review in the EU.
