Theory: picture of Apple store plus picture of truck with a few pallets of something vaguely electronic was not an intercept of a shipment of items for the bad guys, but a shipment of untraceable/encrypted iPhones for the good guys and potentially anyone who flipped. Gotta have secure comms, right? Perhaps reflected picture in oval office is simply rubbing it in.
Note that Tim Cook grew up in a world where he could be meaningfully persecuted for being gay, and his stance on privacy has generally reflected that. It could very well be that he is disgusted with the state of affairs on the other side as well (meaningfully persecuted for not being corrupt/pedo/whatever).
Food for thought.
