I'm reminded of early Unix, with default permissions that made one's files public, in the spirit of sharing. Well before one could Google, I wanted good examples of TeX vitas, so I searched all unprotected files of every math department server I could access. Some people were horrified to learn that this was possible or that I had done this. That most people do not choose 802.11w is a similar state of ignorance. Yes these are public broadcasts. The laws are substitutes for more thoughtful engineering. We have little privacy on the internet; that ship has sailed, through similar ignorance. It's worth worrying about doorbells, but that's not the big picture.
