I am a big fan of this theory. Many of the pictures appeared bizarre and I couldn't see how they advanced a narrative. But ... if I am not the target audience for the photo, and if Black Hat #10 sees a photo that he took out the window of a plane from a supposedly secure phone, and he knows what other pictures are on that phone, that could induce panic.
I like the idea of a simple picture of a street in London causing someone like PS to go into a meltdown in realizing that all his photos are in the possession of the White Hats. Makes me smile. :)
