Privacy matters; privacy is what allows us to determine who we are and who we want to be.

The most important thing to the United States is not being able to attack our adversaries, the most important thing is to be able to defend ourselves. And we can't do that as long as we're subverting our own security standards for the sake of surveillance.

A zero-day exploit is a method of hacking a system. It's sort of a vulnerability that has an exploit written for it, sort of a key and a lock that go together to a given software package. It could be an internet web server. It could be Microsoft Office. It could be Adobe Reader or it could be Facebook.

We decentralise the ability to decide the level of publicity that's attached to any of our communications.

We're opening the doors to people launching missiles and dropping bombs by taking the human out of the decision chain for deciding how we should respond to these threats. And this is something we're seeing more and more happening in the traditional means as our methods of warfare become increasingly automated and roboticized such as through drone warfare.

[Bill] Binney designed ThinThread, an NSA program that used encryption to try to make mass surveillance less objectionable. It would still have been unlawful and unconstitutional.

The NSA was actually concerned back in the time of the crypto-wars with improving American security. Nowadays, we see that their priority is weakening our security, just so they have a better chance of keeping an eye on us.
