Social media companies are suing California, going after a new law restricting their sites' use for children. Google, Meta and Tik Tok separately filed the lawsuits in federal court this week. The law restricts companies from targeting children younger than 16 with "addictive" social media content that supporters say is designed to keep them scrolling for hours. It bars social media sites from providing features like autoplay and recommended content displays to teenagers and young children. The companies are citing their First Amendment right to free speech and the Communications Decency Act, which protects online platforms from being sued due to content posted by third parties.
