"due to Third Party Doctrine, users forfeit their legal right to privacy by merely making it possible for sysadmins to access their information. This means the sysadmins can legally share users' information and passwords with additional third parties, and the NSA can legally spy on it all, without any need for a warrant or probable cause."

This sounds super fishy to me; feels like a misinterpretation made through tin-foil lenses. Citation please?
