While I agree this would be hilarious, and would want them to do it, it scares me that it's possible. That they know who is using it and apparently keep a database of certain users whom they can then blackmail. It's probably just an empty threat though and I'm taking it too seriously.
We do have privacy laws today (USA user), but they are so weak that near my office I regularly see ads advising businesses to treat it as a liability problem and instead buy insurance as a faster and cheaper alternative to good practices.
And it works! This approach should not be feasible to address the costs of violating user privacy. It reiterates to me that we are far too lax.
