I'll accept the point that maybe hipster or path are not (yet) sifting through the data they obtained, however, sometimes startups go bankrupt and someone buys whatever assets are left over. Address data may get sold to a buyer with a different view of privacy. Servers may get hacked and data gets lost. Keep in mind that if you're using hipster/path you're not only risking your data but also the private data of anyone you have in your address book. It's one thing if friends of mine decide that they hand out their phone number, it's another thing if they decide to hand out mine.
