While there is a nugget of truth in that quote, it is also a vast simplification. There is a (somewhat) symbiotic relationship between FB, you, and FB's advertisers. If any one of them are abused too badly, the combined organism will die. That means FB has to create a product people are interested in using and has to protect their privacy just enough while giving their advertisers what they need to successfully market products.
