I think demonizing your adversary is as old a trick as any, really. We have seen the end of the one-way media era, in which people believed that other people around the world all sort of thought the same thing about most things, but of course it was never so.

I also agree that it should be fairly trivial to hack up some bluetooth device with whatever buttons you need and have it relay using your phone to some server, then you just push those buttons in your pocket, virtually undetectable.
