For too long, I have kept quiet. For too long, I convinced myself that what we were doing at Facebook—bringing people together and uniting humanity in common purpose—was so important that I dared not jeopardize it by speaking out. But now, I realize I have a duty to talk about what I saw. I was a high-level employee at Facebook for five years, and during that time, I was responsible for burying thousands of news reports about Mark Zuckerberg’s human zoo.
