You are approaching this as if you broadcast something into the common airwaves it is yours and your secret, while I maintain it is no different than yelling that thing out your open windows and then claiming no one can listen to you. Just because it requires a trivial bit of technology to 'listen' to a radio broadcast doesn't make it any different than blasting sound or light waves. This is your issue -- you think that radio waves are somehow distinct from sound or light, when it is just another version of such things.
