Ohio’s largest public employee pension fund is suing Facebook — now known as Meta — alleging that it broke U.S. federal securities law by purposely misleading the public about the negative effects of its social platforms and the algorithms that run them.

The lawsuit by the Ohio Public Employees Retirement System specifically claims that Facebook buried inconvenient findings about how the company has managed those algorithms as well as the steps it said it was taking to protect the public.

The suit also contends that Facebook knew that its platform facilitated dissention, illegal activity and violent extremism, but refused to correct it. The Associated Press and a coalition of other news organizations have reported extensively on Facebook’s actions, internal dissents that warned of these problems and related issues around the world based on internal company documents, now known as the Facebook Papers, leaked by the data scientist and former Facebook employee Frances Haugen.

“Facebook said it was looking out for our children and weeding out online trolls, but in reality was creating misery and divisiveness for profit,” said Ohio Attorney General Dave Yost 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.”
