Zuckerberg to testify in landmark social media addiction trialMark Zuckerberg, the 41-year-old head of Meta, is the most anticipated witness in the trialLOS ANGELES (UNITED STATES) - Meta CEO Mark Zuckerberg is set to testify Wednesday at a groundbreaking social media addiction trial, summoned by lawyers representing a plaintiff who alleges Instagram and other platforms were deliberately designed to make young users addicted. The trial will mark the first time the multibillionaire will address the safety of his world-dominating platforms directly before a jury. - 'Problematic use' -Instagram chief Adam Mosseri was the first Silicon Valley executive to testify on February 11, in which he told jurors he rejected the concept of social media addiction in favor of "problematic use" -- Meta's preferred terminology. The day before, the plaintiff's lawyers called psychiatrist Anna Lembke to explain how social media can act as a "gateway drug" for young people, rewiring their still-developing brains toward addictive behaviors. YouTube CEO Neal Mohan was also scheduled to testify, but lawyers for the plaintiff on Tuesday said they would call another YouTube executive instead.
