How is this any different than "exploiting" data from Facebook, or mailing lists of people who did not check the box next to the words "I don't want my information to be shared with third-parties"?

How does an unsecured Wi-Fi network, emanating signal out into the street, deserve some sort of "expectation of privacy"? You deserve no expectation of privacy if your blinds are pulled-up and your windows are open. Why should Wi-Fi be any different, just because users can't be bothered to learn to protect their assets?
