Everyone is ignoring the worst part of this. While very bad, it’s not that Path actually uploaded their address book (I’d venture most store it in “the cloud” already, so true privacy is out the window). The worst part is that Path didn’t even think this would be a problem until it became news. Even 2 years ago I don’t think there was anyone other than malware developers who would think uploading an entire address book of contacts without an explicit approval would be an OK practice. That is a huge cultural shift.
If Path were a desktop app in 2010, they would be competing with AntiVirus and Spyware blockers who would be racing to provide protection to their users.
In just a short time, a practice that would be reserved for illegal and dubious software was adopted by what seems like a mainstream startup. It’s electronic moral decay.
Apple doesn’t get a free pass either. Why in iOS 5 a sandboxed app can access an address book without alerting the user is beyond me. Addresses, calendar data, geolocation, and the ability to make a call are sacred API’s and should have obvious UI and/or warnings. Geolocation does have an interstitial alert. Phone calls have an obvious UI. Address and calendar data need to have an alert before the app is granted access.
