Yes, but leaks of pre-release iOS software can&#x27;t be installed on locked phones as a means of unlocking them, so the risk is not nearly the same.<p>If you really want to carry this analogy to term, fine, I&#x27;ll concede that you can&#x27;t be 100% sure that a physical key wasn&#x27;t copied before you destroy it, but then you must take into consideration the complexity of manufacture and duplication - if the complexity of duplication is high, and you only make one, and guard it at all times, you can have a fairly high confidence (barring ridiculous film plots) that the key you&#x27;re destroying is the only one.<p>With digital things, the complexity of duplication is beyond trivial. One copy leaks, and instantly there are tens of thousands, if not millions of copies in all corners of the internet. Physical objects simply do not behave this way.
