Last month, the Wall Street Journal began publishing a series of reports called “The Facebook Files.” Based on leaked internal documents, the series highlights how Facebook has stoked fear, anger, and division in order to increase user engagement—and how it then failed to effectively fight the spread of misinformation and the use of its platform to exploit and abuse vulnerable communities around the world. This week, Frances Haugen, a former data engineer at Facebook, revealed herself to be the whistle-blower who leaked the documents to the Journal, and on Tuesday she provided explosive testimony before a Senate subcommittee. The company has announced no significant plans to change its operating structure. Andrew Marantz joins Dorothy Wickenden to discuss the latest uproar over Facebook, and what can be done to drastically change its practices.
