Copyright is a more-apt comparison than it may appear: the trope of citizen information and data is that hey, once you give it to a third party, the government can get access to it on the slightest of pretexts (Smith v. Maryland).
Contrast this with copyright: every single use and re-use must be licensed. Aside from the first-sale doctrine (which has been getting whittled in the digital age), a movie which licenses your favorite Skrillex cut cannot turn around and allow other people to use it willy-nilly, the way Comcast and Google can do with your emails.
