The key analogy starts to break down at some point. The &quot;master key&quot; as you put it is that Apple has the engineers, experience, and digital key that enables them to create a second key for any IPhone manufactured pre secure enclave. The argument here is that once Apple creates that second key the effort required to steal it is significantly lowered. You can&#x27;t steal something that doesn&#x27;t exist yet.<p>It&#x27;s more analogous to forcing everyone to use a shorter password composed of only numerical digits because it makes brute forcing easier.<p>The mere existence of this new less secure IOS makes Apple even more of a target. The slightest chance that it could leak would render more than the hundreds of iPhones the FBI want&#x27;s to unlock completely insecure.
