&gt;  No employee at Apple is going to call him out on it, and everyone else can be written off as speculating.<p>I wouldn&#x27;t put it past the NSA to have snapped up a former iOS developer for explicitly the purpose of breaking into iPhones.  An ex employee could certainly call him out.<p>&gt; Additionally, that letter is written with very carefully fuzzy language so as to remain true-ish.<p>Cook is trying to be as clear as possible to a public who doesn&#x27;t understand encryption or why Apple is standing up to the FBI.  That&#x27;s a lot to swallow, and yes his letter is carefully worded for good reason.  Given that there is a backdoor that Apple could create, it&#x27;s not unthinkable that with more details, 3rd parties could figure out how to get in too.
