Facebook whistleblower Frances Haugen testified before the Senate Committee on Commerce, Science, and Transportation in early October. She appeared before lawmakers after making available a large number of internal Facebook documents to reporters. Stories based on the leaked research materials appeared in The Wall Street Journal and CBS’s 60 Minutes before Haugen’s testimony. The former Facebook whistleblower alleged that the company knows exactly how toxic its social networks can be. Its algorithms push unsafe content to increase online engagement and drive up ad sales, she explained.
