Well, if that situation were to come, I'm sure that I'd philosophically feel the same. But it would still be very, very hard to give away my information despite knowing that it's already in someone else's database. Imagine that you have the risk of being blackmailed with certain information. I think that anyone would be unwilling to give that away. I can't be blackmailed with mine, but it's still private for a reason (or for the lack of a reason of it being publicised).

I'm not sure what I would do in such a situation. I hope it doesn't come during my lifetime.
