Apple has explicitly stated they can do what is asked at every opportunity.<p>You ever been responsible for writing secure software?  It isn&#x27;t easy.  Locking it down to a single device is in principle possible.  No one wants to be responsible for really doing it though if they can avoid it.  Especially not when it is obvious this is not a one time thing.  Not at all.  You think every device manufacturer can do it without error too?  There will be a lot of secret cracking tools if this gets started.
