This is a great counterpoint to Google's insistence that there doesn't need to be a discrete "Internet access" permission in Android. Their position is that if apps are all well-siloed then it doesn't matter if they chat to the Cloud because they can't leak data to which you have denied them access ( contacts, photos etc ) But that's only true for on-device data; here's an app that's relaying data from a Bluetooth source. Data which the user would prefer it didn't send to the Cloud. But without rooting there's no way to stop it doing so. Please Google, give us the ability to block Internet access.
