From your link, it's quite clear they intend a political statement — about privacy in the age of search engines and social networks and the economic underpinnings of same.

Why is Google free? Because you are only the user, not the customer. The customers are the advertisers who pay Google to show you targeted ads. Of course, Google has to please both its users and its customers, or else it won't have enough of the former to satisfy the latter. Same for social networks, media sites, and pretty much everybody else who publishes free content or offers free services that cost money to produce. That's how the internet is paid for.

I get the impression AOS is less than pleased with that arrangement. Clearly, it frustrate them that so many users are pleased with how the internet has evolved to work. They're hoping their outrageous offer will wake up, er, raise the consciousnesses of those users. "Users of the world, unite: you have nothing to gain but your privacy!" Or something like that.

If it's art, it is performance art, where the performance consists solely of the business proposition.
