The most striking thing Snowden has revealed is the depth of what the NSA and the Five Eyes countries [Australia, Canada, New Zealand, Great Britain, and the US] are doing, their hunger for all data, for total bulk dragnet surveillance where they try to collect all communications and do it all sorts of different ways. Their ethos is "collect it all."

That's a question you'd have to present to people in the White House.

People are starting to understand that the devices we carry with us reveal our location, who we're talking to, and all kinds of other information.

We've already seen shifts happening in some of the big companies - Google, Apple - that now understand how vulnerable their customer data is, and that if it's vulnerable, then their business is, too, and so you see a beefing up of encryption technologies. At the same time, no programs have been dismantled at the governmental level, despite international pressure.

I think it's radical to censor information because the government asks you to. That's radical.

We don't stand here alone, it's possible through the great organisations that support us. The disclosures that Edward Snowden revealed aren't only a threat to privacy but to democracy, when the most important decisions made affect all of us. Thank you to Edward Snowden. I share this with Glenn Greenwald and other journalists who are exposing truth.

One of the things that I think is true is that encryption actually is able to secure our communications, that every individual can use encryption, and that it's accessible and in many cases free.
