"You're still accessing someone's private (albeit unsecured) network." I guess that's the whole issue right there - Is something that is being broadcast, possibly 40m outside my house, still private? At what point does a signal become so large that it defaults to a public broadcast? To me it makes sense that if I access your wifi, but can only get that signal by standing in your house, by all reasoning that is a private network. However if I can stand on a street corner and still access your signal, it's public. Of course I guess with strong enough hardware you could access both regardless, so I really don't know.
