They walked into a glass building (unencrypted wifi location), unzipped their flies, sat down, and are totally unaware they did so. Someone would have noticed eventually - would they rather be potentially gawked at behind the one-way mirror that's always been there but they never noticed (WireShark), or told, allowing them to cookie-block the ones who do so?
As to the volume of the telling, what if near enough to everyone were doing this? You would probably become the crazy person at the intersection, telling everyone the end of privacy is near, repent and use SSL. But at least this way you can demonstrate that yes, their flies are down, in a way they can see, rather than having to take your word on it.
