Meta Platforms Inc. (NASDAQ:META) has lost an appeal in a privacy dispute with the U.S. Federal Trade Commission (FTC). The U.S. District Court for the District of Columbia rejected Meta's request to intervene in the case concerning the Messenger Kids app. The FTC had previously charged Meta with deceiving parents about their children's communication options on the app and suggested revising a 2019 settlement that included a $5 billion payment by Facebook. Meta, which relies heavily on digital ads for revenue, called the FTC's charges baseless and is considering further legal actions. This legal issue adds to ongoing concerns about harmful content on Meta's platforms, including hate speech and misinformation, as well as safety measures for teenagers on Instagram.
