What I think is interesting, which they don't address in the article, is at least for Android (I don't own an iPhone) the app store tells you that this is possible. But not exactly. In other words, it'll say: This app uses the internet, and this app uses geolocation - but you have to make the conclusion that the pieces are all there for the app to transmit your location to anyone it chooses. Being a programmer I'm not surprised that all these apps do it, but if I was an average consumer, these types of atomic warnings do not generate the conclusions that they do for me.
