The Senate heard testimony Tuesday from former Facebook employee Frances Haugen, who came before the Subcommittee on Consumer Protection, Product Safety, and Data Security to raise the alarm about practices in Facebook that she said demanded congressional action. …After the hearing, Facebook issued a statement suggesting it was open to having the government “begin to create standard rules for the internet.” The hearing itself was initially prompted by an expose by The Wall Street Journal that showed Facebook had hidden research data on the harmful effects of its platform. However, the conversation between Haugen and the subcommittee delved deeper into the company’s practices.
