I'm ultimately satisfied that we know a little bit more about how the world really works.

Before 2013, if you said the NSA was making records of everybody's phone calls and the [Government Communications Headquarters] was monitoring lawyers and journalists, people raised eyebrows and called you a conspiracy theorist. Those days are over.

The question is: Particularly in the post-9/11 era, are societies becoming more liberal or more authoritarian?

Congress hasn't declared war on the countries - the majority of them are our allies - but without asking for public permission, NSA is running network operations against them that affect millions of innocent people. And for what? So we can have secret access to a computer in a country we're not even fighting?

You have ceded the concept of your own rights. You've converted them into something you get as a revocable privilege from the government, something that can be abrogated at its convenience. And that has diminished the measure of liberty within a society.

[Sovereignty] would break the American monopoly, but it would also break Internet business, because you'd have to have a data center in every country. And data centers are tremendously expensive, a big capital investment.

There was a real choice when [Barack Obama] became president. It was a very difficult choice - to say, "We're not going to hold senior officials to account with the same laws that every other citizen in the country is held to," or "This is a nation that believes in the rule of law."
