There is a saying that if you get something for free, you should know that you're the product. It was never more true than in the case of Facebook and Gmail and YouTube. You get free social-media services, and you get free funny cat videos. In exchange, you give up the most valuable asset you have, which is your personal data.

Censorship no longer works by hiding information from you; censorship works by flooding you with immense amounts of misinformation, of irrelevant information, of funny cat videos, until you're just unable to focus.
