LinkedIn provided a pop-up window which, in small print, if you had logged in via Google or Facebook, notified users in legal terms that their e-mail contacts could (potentially, under some circumstances) be accessed.

Thus, in legal proceedings, the user was entirely informed of the possibility of this situation arising.

For future users, this sets a precedent that users are aware of the terms and conditions (as they have always been), and no further accidental leaks of personal information will occur.
