I have no moral problem with considering the Girls Around Me devs to be at fault, but in practice it's like getting angry with individual spammers. It's futile. Pretty soon others will leap onto the publicity created by the furore and create something functionally equivalent. It seems to me the practical approaches to improving the situation are a) Embarrass Foursquare, Facebook et al into not sharing the info, b) Educate people into being more careful what they put online or c) Work on alternative social networking infrastructure that's more respectful of people's privacy. Whether or not we get upset at the Girls Around Me people is just a distraction.
