Nobody cares about your private life unless you are trying to affect others negatively.

Correction: "Nobody cares about your private life unless you are trying to affect others negatively, OR if they can use that information for personal gains, even if at a loss to you."

The state and its agents don't use information for personal gains, their job and passion concerns society as a whole, and they want to make sure that no bad guys come in.
