I'll sometimes surrender some privacy for some form of safety or convenience, but that safety/convenience has to exist, not be theoretical.

Positive example: I use Google Drive. I know full well Google could read and analyze all my shit if they wanted to. I surrender to that possibility in exchange for the very cheap and convenient online storage I get.

Negative example: Fuck the TSA and all its theatrics. Those aren't useful. Please do convince me they are; I don't see anyone even trying to pretend they are.
