A system where users can recover their devices if they successfully hold onto their private keys is much better than a system where they can't recover their devices at all without Apple's reluctant help.
Maybe for power users, sure. But for regular people (Apple’s biggest market) it’s not an issue: they just register their devices and don’t have to worry about it.
Isn’t the issue in this case that the use didn’t enable “find my mac” in the first place, the thief was able to tie the device to their account and then brick it?
I assume he would’ve been able to recover it if he had “held on to his private key” (having the device be linked to his account being the current equivalent)?
