The majority of people in developed countries spend at least some time interacting with the Internet, and Governments are abusing that necessity in secret to extend their powers beyond what is necessary and appropriate.

When you think about the abolition of slavery for example, for the ruling class with the rich white people owning plantations and states, and things like that, slavery was to their benefit. To oppose it didn't make any sense at all on a rational basis. But on a rights basis, on a principle basis, it made obvious, overwhelming sense.

[Bill] Binney will argue with you all day about ThinThread, but his idea was that it would collect everything about everybody but be immediately encrypted so no one could read it. Only a court could give intelligence officials the key to decrypt it. The idea was to find a kind of a compromise between [privacy rights and] the assertion that if you don't collect things as they happen, you won't have them later - because what the NSA really wants is the capability of retrospective investigation.

We don't have a great clash of civilizations, a clash of ideologies, a clash of alternative models, where governments thought to themselves, if we go too far, if we sort of trample unreasonably on rights, we'll give birth to a political movement which will cost us our credibility, and will possibly cost us our offices, because people will vote for the other team, the other guys.

We're now more than a year since my NSA revelations, and despite numerous hours of testimony before Congress, despite tons of off-the-record quotes from anonymous officials who have an ax to grind, not a single US official, not a single representative of the United States government, has ever pointed to a single case of individualized harm caused by these revelations. This, despite the fact that former NSA director Keith Alexander said this would cause grave and irrevocable harm to the nation.

Where are we going to reject that easy but flawed process of letting the intelligence services do whatever they want? It's inevitable that it will happen. I think it's going to be where Internet businesses go.

We have the right of revolution. Revolution does not always have to be weapons and warfare; it's also about revolutionary ideas.
