"If you don't pay for it, you are the product". Facebook creates detailed profiles on both its users and on people who don't have an account. It's a dream come true for any spy agency: the world's biggest people database, where people report on themselves and on each other. Their algorithmic newsfeed has a huge influence on how its users see the world, allowing companies and governments to manipulate their perception, and even their mood.
