The Globe and Mail reports in its Friday edition that Meta chief executive officer Mark Zuckerberg faced questioning in court over claims that his company creates addictive social media that harms young users. The Globe's Gus Carlson writes that the lawsuit was filed by a 20-year-old California woman who alleges that Meta and other big technology companies deliberately engineer their platforms to target young users, particularly "tweens" under 13. She claims that as a young elementary school user, she became addicted to Meta's Instagram and Google's YouTube, leading to anxiety, depression, body dysmorphia and suicidal thoughts. She seeks to hold the companies accountable. The trial could cost Meta billions and reshape social-media accountability, serving as a bellwether for numerous similar lawsuits against Meta, Google and other platforms. Meta and Google have denied the allegations that they target young users by rigging their platforms with addictive hooks. Mr. Zuckerberg told the court that Meta's goal for Instagram is to provide long-term utility and value, not a short-term addictive fix. Tracking data shows that precious few parents have enabled the parental controls available on behalf of their children.
