Clearly you don't know about the mole(s) among the ranks.
Proper encryption isn't vulnerable to moles. If it's designed correctly there's no back door or shortcuts in existence, there's nothing to steal and give out.
The only thing right now that qualifies with that is the private key to their software signing certificate that tells the iPad the firmware you just uploaded to it is genuine and to allow the installation to take place. Pretty sure Apple keeps really tight control over that particular key, and will aggressively bar-b-qua anyone they catch copying it.
That sort of data exists in only there or four places in the world, inside very secure safes with singularly limited physical access, and only comes out when the GM firmware update needs to be signed.
