John Naughton:

During the hoo-ha, one of the spooks with whom I discussed Snowden’s revelations waxed indignant about our coverage of the story. What bugged him (pardon the pun) was the unfairness of having state agencies pilloried, while firms such as Google and Facebook, which, in his opinion, conducted much more intensive surveillance than the NSA or GCHQ, got off scot free. His argument was that he and his colleagues were at least subject to some degree of democratic oversight, but the companies, whose business model is essentially “surveillance capitalism”, were entirely unregulated.
 He was right. “Surveillance”, as the security expert Bruce Schneier has observed, is the business model of the internet and that is true of both the public and private sectors. Given how central the network has become to our lives, that means our societies have embarked on the greatest uncontrolled experiment in history. Without really thinking about it, we have subjected ourselves to relentless, intrusive, comprehensive surveillance of all our activities and much of our most intimate actions and thoughts. And we have no idea what the long-term implications of this will be for our societies – or for us as citizens.
