Does a reasonable person still have an expectation of privacy if not only does he leave the door open, he sits by while a supposed intruder walks in and out not once, not twice, but one hundred thousand times (in addition to unknown numbers of other intruders multiplied by unknown numbers of more times)? Not only was the organization so derelict in their affairs that they failed to protect sensitive customer data, they didn't even notice the "crime" had taken place (a hundred thousand times), and in fact, would never have noticed, and would prefer not to have noticed, had they not been forced by the threat of public disclosure.
