One sad consequence of this is that people don't feel permitted to try understand Internet infrastructure, so I'm really grateful to groups like Free Press and other nonprofits who are trying to make the issue urgent and comprehensible. And Andre Blum's book Tubes is great on this topic.

I try to look at the evolution of these utopian claims. In the late '60s there was an assumption that the wealth generated by industry would be taxed and then put into social programs and it would provide a baseline of stability that would allow people to have the time for self-expression; and that social contract has eroded over the last four decades and now it's every person for themselves.

I work for free all the time, as a writer but also as an activist. The decisions we have to make as individuals are really fraught but also can be really wonderful and we're all navigating this reality to the best of our abilities. But, again, I wanted to take a step back and look at the broader context.

It's very complicated. There's been this broader mechanism, an industry, which wants people to use free services, from the old days of advertising-supported papers and magazines, to ad-supported free television.

I think that overall, ultimately the impact of advertisers calling the shots is a more cloying, complacent culture. For example, it was just announced that Unilever is branding environmental content at The Guardian. How radical or pointed can that content be?

It's always the balance between the individual's subjective experience and the social structural condition. As individuals we have access to more than we've ever had before. Giving up our data seems a small price to pay, especially if, as you say, we don't feel we have anything to hide.

A big factor is that the enthusiast camp's values are really rooted in Silicon Valley and in these supposedly new business models. But again, I think this such an interesting moment because things like the NSA revelations are really forcing people to recognize the connections between corporate and government surveillance.
