Meta Platforms has agreed to pay US$17 billion and add child-safety measures to its Facebook and Instagram platforms to end a landmark trial over teen social media addiction and settle claims filed by 47 US states, state attorneys general announced on Wednesday.California, Colorado, Kentucky and New Jersey were among 29 states that sued the tech giant in 2023, but the deal cuts short the trial, which was expected to see CEO Mark Zuckerberg take the stand before a jury in federal court in California.The agreement is worth US$353 million in Virginia alone and is one of the biggest in state consumer protection history, Attorney General Jay Jones said in a statement.“For years, Meta intentionally deceived the public about the addictive and harmful design features that have wreaked havoc on youth mental health,” Jones said. The settlement “will put an end to these dangerous practices and deliver meaningful relief that will protect children from online harm”.Meta said in a blog post that it was “building on our long-standing efforts to empower parents and support teens”.“Ensuring teens have a safe and productive experience on our platforms is an absolute imperative for Meta,” the company said. “We want to get this right for parents and teens, and that’s why we partnered with state attorneys general to set a new industry standard.”
