Destroying the privacy of several billion people is not an adequate price to pay for capturing a dozen or even a hundred bad guys.
Sure it did get them some. So would carpet-bombing New York City. Success alone is a worthless measure without taking cost into account.
Stasi couldn’t record what newspaper articles you were reading. For how long. And in what order. That, along with pretty much every thought you have ever explored while sitting at a computer, is now part of your permanent record – even if you never told a single human being.
I've heard quite a lot of people that talk about post-privacy, and they talk about it in terms of feeling like, you know, it's too late, we're done for, there's just no possibility for privacy left anymore and we just have to get used to it. And this is a pretty fascinating thing, because it seems to me that you never hear a feminist say that we're post-consent because there is rape. And why is that? The reason is that it's bullshit.
We can't have a post-privacy world until we're post-privilege. So when we cave in our autonomy, then we can sort of say, "well, okay, we don't need privacy anymore, in fact we don't have privacy anymore, and I'm okay with that." Realistically though people are not comfortable with that. Because, if you only look at it from a position of privilege, like, say, white man on a stage, then yeah, maybe post-privacy works out okay for those people. But if you have ever not been, or if you are currently not, a white man with a passport from one of the five good nations in the world, it might not really work out well for you, and in fact it might be designed specifically such that it will continue to not work out well for you, because the structures themselves produce these inequalities.
So when you hear someone talk about post-privacy, I think it's really important to engage them about their own privilege in the system and what it is they are actually arguing for.
