The Apple Psi System [pdf]
This is incredibly annoying.  They're providing all of this information which says that this program that runs on our devices is incredibly safe if we're not bad people.  That the people at Apple and then law enforcement don't see anything about our photos until there is a human set threshold hit by a human programmed algorithm.  Technically, this should be sound since the proof has checked out with multiple cryptography experts.  But none of that matters.The Apple PSI System is spyware.They are providing all of this info to justify putting spyware on our devices.  They are attempting to put spyware on our devices to see if we can be sent to jail.  That's all that matters.  That is the end effect.Apple is justifying putting SPYWARE ON ALL OF THEIR PHONES.  Any discussion of the technical merits of a SPYWARE system implemented against you is missing the point.  It should not exist.
