The revelations-including that Facebook knew Instagram was worsening body image issues among teenagers and that it had a two-tier justice system-have spurred criticism from lawmakers, regulators and the public. “Facebook, over and over again, has shown it chooses profit over safety.” Haugen gave many of the documents to The Wall Street Journal, which last month began publishing the findings. “I’ve seen a bunch of social networks, and it was substantially worse at Facebook than what I had seen before,” Haugen said. So she copied pages of Facebook’s internal research and decided to do something about it. The company repeatedly put its own interests first rather than the public’s interest, she said. In an interview with the TV show 60 Minutes that aired on Sunday, Haugen, 37, said she had grown alarmed by what she saw at Facebook.

A product manager who worked for nearly two years on the civic misinformation team at the social network before leaving in May, Haugen has used the documents she amassed to expose how much Facebook knew about the harms that it was causing, and provided the evidence to lawmakers, regulators and the news media. On Sunday, Frances Haugen revealed herself to be "Sean," the whistleblower against Facebook.
