Meta Platforms is facing its most consequential legal challenge yet, as a trial in Oakland, California, forces the company to defend the very features that critics say make Instagram and Facebook dangerously addictive for young users. Four states—California, Colorado, Kentucky, and New Jersey—are suing Meta, alleging that its platforms are deliberately designed to keep teenagers hooked by exploiting psychological vulnerabilities. The company has warned that the theoretical penalties could reach $1.4 trillion, but the more immediate question is what happens to the product itself if the court orders Meta to restrict core mechanisms like infinite scroll, autoplay, and algorithmic recommendations.

The comparison to Big Tobacco is frequently invoked, but Larry Magid, a longtime online-safety advocate who has worked with Meta on safety issues since 2005, points out a crucial difference. Cigarettes never learned what each smoker craved next. Instagram does. Its recommendation engines constantly refine what users see, while infinite scroll removes any natural endpoint and autoplay serves the next video without waiting for a request. Magid once preferred a different analogy: chocolate. Social media, he argued, can offer genuine benefits—maintaining friendships, finding communities, organizing causes. But he realized the metaphor broke down. "A chocolate bar doesn't refill itself," he told Fortune. "The algorithms change the whole nature of it." Magid now describes the experience as a grocery store that automatically delivers more chocolate bars whenever it notices the supply is low. "It encourages gluttony," he said.

Magid's own experiment with turning off the algorithm is instructive. He switched his Facebook feed to chronological order, removing the recommendation engine. The result was boredom. "I actually went back to the algorithm because I found it was benefiting me in some ways," he said. That tension illustrates the dilemma Meta faces. The features under scrutiny are not obscure corners of Instagram; they are central to how people discover content and decide whether to keep scrolling. Simply eliminating them might hurt the platform's appeal. Magid advocates for a more balanced approach: make recommendations less aggressive, prioritize a user's chosen social graph—friends, communities, explicit interests—rather than algorithmically predicted engagement.

Magid has observed the platform's evolution from a network built around interactions among friends into one dominated by recommendations, influencers, and strangers. He currently serves on Meta's Safety Advisory Council and Youth Advisory Council. Meta does not fund his nonprofit, ConnectSafely, but compensates it for advisory work. His proximity gives him a unique view of a growing problem: the Instagram an adult sees often looks nothing like the version served to a teenager. Magid's own feeds are benign—aviation content, news, occasional political disagreements. But teenagers describe something darker. "I am told by minors, by high school kids and young adults, that they have a very different experience than I do," he said. "They are seeing misogyny, homophobia, racism."

The same personalization technology that surfaces Magid's airplane content can also learn what captures a teenager's attention. That does not make recommendation algorithms inherently harmful, Magid argues, but it raises the stakes of what platforms optimize for and how aggressively they serve more. He believes Meta could dial back some of these systems for younger users without devastating revenue. Meta has told Fortune that less than 1% of its revenue comes from teens on Instagram. The company disputes the states' allegations, arguing that no harm has been proven and that it has implemented strong protections.

Magid does not want the answer to be kicking teenagers off social media entirely. He still values online communities and expression for young people. Instead, he wants Meta to build a version of Instagram that gives teenagers more control over what reaches them and puts less emphasis on maximizing engagement. The challenge is not making Instagram something teenagers don't want to use, but making an Instagram they can more easily choose to stop using.

Beyond the product changes, the trial is creating a public record of internal documents, testimony, and allegations about what Meta knew regarding potential harms to young users. That information could have lasting consequences for the company's board. Stavros Gadinis, a professor at UC Berkeley School of Law who specializes in corporate governance, explains that directors typically enjoy broad protection when they rely on legal advice. But as more evidence surfaces, "the plausible deniability that they were able to defend up to this point retreats a little bit," he told Fortune. Even if Meta wins the case, the board must consider why. A victory based on a procedural failure sends a different signal than one rejecting the states' underlying theory. Gadinis notes that the legal bar for holding directors personally liable for oversight failures is high, but a loss would be a red flag. "What's done is done," he said. "They cannot change what they've done in the past, but they can always change what they're doing in the future." Meta is already on notice from a separate case in New Mexico, where a jury found the company liable for 75,000 violations of the state's consumer protection law. Meta is appealing. The cumulative effect of these cases may force the company—and its board—to reexamine the systems designed to keep users scrolling, regardless of the Oakland verdict.
