Companies have been shipping apps that collect email lists, GPS, records, phone info, and all manner of other personal info back to their servers. We used to call this what it is: spyware, and it was considered illegal. Usually it is claimed this information is intended to "optimize the app for your personal preferences" but "social" is the new hotness. Often when it comes down to it we find this data is more valued for building marketing profiles of individual consumers.
Comparing these companies to a cute picture of a "docile retriever" being attacked by a pit bull (as if they're the victim!) is just over the top.
