As an individual navigating this reality, you have to make choices to survive. Sometimes you happily work for free if it's something you love and believe in. I'm not categorically saying that working for free is bad. I'm just looking at the broader implications of it, and also challenge this idea - and again, this is an argument made by certain people in the tech world - that amateurs are automatically more pure and will triumph over stodgy professionals.

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.

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?

All the utopianism of the early days of the Internet seems to have dissipated. But I don't want us to lose that utopianism altogether, even if it was naïve and ill-informed and sometimes silly. Rather I want us to ask about the obstacles that are preventing the good stuff from coming to fruition. Let's investigate and think about creating something worthwhile instead of assuming that there is an inevitable track of increased centralization, consolidation, and commercialization that we can't do anything about.

It wasn't that people wanted things for free and asked for advertising to fund it - it's that these companies wanted to amass an audience whose "eyeballs" they could sell, and they gave people things for free to do that. Free services and content has been foisted upon us because there wasn't the will power to explore other options.

To go from the vision that we would all be free to express ourselves creatively because our material needs were being met, to this reality where nobody has money, people are unemployed, and the machines are harnessed by the lucky guys who Facebook or Google and we're supposed to be happy just to contribute content to their site.

My point, though, is that if lines have indeed shifted, it's not so much that the younger generation just doesn't care, it's that we have ceded more and more of our public life over to the private sector. If you grow up with advertising at school, you have come of age in a sold-out world.
