I also used to be an engineer at Facebook. Definitely the corporate culture wouldn't allow anything like this. Believe it or not, many FB engineers have some kind of free software / civil liberties background in their past, and most people don't seem to realize that A) they have options, they can and would walk out if they witnessed anything shady B) the company has enough fake scandals wound up by the press as it is, to risk doing something genuinely evil for short term gain, and have a former employee eventually blow the whistle on. One controversy after the other, during my time at Facebook I witnessed the chasm between the mostly innocent motivations behind a product feature, and what the press / outside world made of it. This experience probably taught me as much about media cycles and conspiracy theory dynamics, as it did about engineering.
