Ohio Attorney General Dave Yost has filed a lawsuit against Facebook, alleging the social network misled the public on the negative effects its products have on the health and well-being of children.The lawsuit, filed on behalf of the Ohio Public Employees Retirement System (OPERS) and Facebook investors, alleges that from April 29 through Oct. 21, 2021, Facebook and its senior executives violated federal securities laws by purposely misleading the public about the negative effects its products have on the health and well-being of children and the steps the company has taken to protect the public. "Facebook said it was looking out for our children and weeding out online trolls, but in reality was creating misery and divisiveness for profit," Yost said in a statement. "We are not people to Mark Zuckerberg, we are the product and we are being used against each other out of greed."Facebook has been under fire after whistleblower Frances Haugen, a former Facebook product manager, provided The Wall Street Journal with internal documents that exposed the company’s awareness of harms caused by its products and decisions. Haugen went public on CBS’s “60 Minutes” program.Haugen had also anonymously filed complaints with federal law enforcement alleging Facebook’s own research shows how it magnifies hate and misinformation and leads to increased polarization. It also showed that the company was aware that Instagram can harm teenage girls’ mental health.The Journal’s stories, called “The Facebook Files,” painted a picture of a company focused on growth and its own interests over the public good. Facebook has tried to play down their impact. Nick Clegg, the company’s vice president of policy and public affairs, wrote to Facebook employees in a memo Friday that “social media has had a big impact on society in recent years, and Facebook is often a place where much of this debate plays out.”In the lawsuit, Yost alleges Zuckerberg and other company officials knew that they were making false statements regarding the safety, security and privacy of its platforms. Facebook admitted in those internal documents that, "We are not actually doing what we say we do publicly."Yost said the revelations caused a devaluation in Facebook's stock of $54.08 per share, causing OPERS and other Facebook investors to lose more than $100 billion.The lawsuit is seeking to recover that lost value and demands that Facebook makes significant reforms to ensure it does not mislead the public about its internal practices.In May, Yost joined 43 other attorneys general in a letter to Zuckerberg urging him to halt his plans to introduce an Instagram app for kids. Facebook later said it will pause plans for the app, following the mid-September report by The Wall Street Journal that found Facebook knew from its own research that Instagram was harming some teems, especially girls, leading to mental health and body image problems and in some cases eating disorders and suicidal thoughts.
