One of the most frightening things, I think, is the capacity for retroactive searching, so you can go back in time and trace who someone is in contact with and where they've been.

I don't speak Arabic - I know a little to get by, but that's all.

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.

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.

We're definitely in an era where the government wants to keep more secrets and it wants to come after anyone who's exposing those secrets and in many cases exposing government illegality. They're coming after the journalists and they're coming after the whistleblowers. It's not a good sign if the government is expending much energy trying to find out who journalists are talking to.

Snowden has presented us with choices on how we want to move forward into the future. We're at a crossroads and we still don't quite know which path we're going to take. Without Snowden, just about everyone would still be in the dark about the amount of information the government is collecting. I think that Snowden has changed consciousness about the dangers of surveillance.

The free software community should be supported more widely. I’m totally in solidarity with what they do.
