LOS ANGELES — In a groundbreaking courtroom battle that could reshape legal accountability for digital platforms, YouTube’s legal representation mounted a vigorous defense Tuesday against allegations that the Google-owned service deliberately engineers addictive features targeting children.
Attorney Luis Li presented opening arguments before a twelve-member jury, fundamentally challenging the case’s core premise. “It’s not social media addiction when it’s not social media and it’s not addiction,” Li asserted, drawing sharp distinctions between YouTube’s video service and social media platforms like Instagram and TikTok.
The civil trial, unfolding in California state court, represents a bellwether case with potentially far-reaching implications for hundreds of similar lawsuits pending against social media companies nationwide. The litigation centers on claims that a young woman identified as Kaley G.M. developed severe mental health issues after becoming addicted to social media during childhood, beginning with YouTube at age six before progressing to other platforms.
Li systematically dismantled the addiction narrative, noting: “The plaintiff is not addicted to YouTube. You can listen to her own words — she said so, her doctor said so, her father said so.” He characterized YouTube instead as a modern equivalent of television, emphasizing that “more people watch YouTube on television than they do on their phones or their devices. More people watch YouTube than cable TV.”
The defense attorney portrayed YouTube as an educational and entertainment resource rather than a social network, citing internal company communications that he claimed demonstrated executives prioritizing socially beneficial content over viral engagement metrics. “YouTube is selling the ability to watch something essentially for free on your computer, on your phone, on your iPad,” Li stated, comparing the platform to Netflix rather than social media.
This defense followed Monday’s opening statements from plaintiffs’ attorneys who accused both YouTube and Meta (parent company of Instagram and Facebook) of deliberately engineering addiction into young users’ brains to drive engagement and profits.
The trial’s first expert witness, Stanford University School of Medicine professor Dr. Anna Lembke, provided dramatic testimony comparing social media to addictive substances. She explained that the prefrontal cortex—which regulates impulse control—doesn’t fully develop until approximately age 25, making adolescents particularly vulnerable to addictive design features. “Typically, the gateway drug is the most easily accessible drug,” Lembke testified, describing the plaintiff’s early exposure to YouTube at age six.
The outcome of this landmark proceeding could establish critical legal precedents governing technology company liability for user mental health impacts, with implications comparable to historic litigation against the tobacco industry.
