I think the message he's trying to send surrounds the idea of the NSA monitoring everyone without consent.
I like how in all his videos he never really says or does anything at all. All he does is make it obvious that he is recording.
He is trying to show that merely the site of him recording makes the people become uncomfortable, whereas when the NSA does it discreetly it is somehow ok, and no one takes immediate action to stop them like they do in the video.
