Four landmark lawsuits could reshape how social media platforms operate

Two decades ago, when social media first began its ascent, the promise seemed straightforward: technology that would dissolve barriers between people and democratize information. Today, Meta, Google, TikTok, Snapchat, Discord, and Roblox are defending themselves against thousands of lawsuits in American courts, many of them alleging that these platforms have instead inflicted measurable harm—particularly on children. The cases are no longer theoretical. This year alone, Meta and YouTube lost a jury verdict to a young woman who claimed the platforms' design had fed her addiction and damaged her mental health; a jury ordered them to pay her six million dollars combined. Meta also lost a separate case brought by New Mexico's attorney general, which accused the company of misleading the public about child safety while knowing that young users were being sexually exploited on its platforms. Both companies have said they plan to appeal.

What makes this moment significant is not just the individual verdicts, but their cumulative weight. Legal scholars and regulators are watching closely. Eric Talley, a lawyer and professor at Columbia Law School, notes that the wave of litigation is shaping public perception in ways that will likely influence elections and drive new legislation for years to come. Alexis Shore Ingber, a communications law expert at Syracuse University, describes what is happening as an inflection point. The cases are being litigated primarily in California, where all the major platforms are headquartered—a phenomenon known as the "California effect," in which legal changes in the state tend to ripple outward and become national precedent.

Four cases in particular are being watched as potential bellwethers, cases that could reshape how platforms operate. The first is a multidistrict litigation brought by school districts against Instagram, YouTube, Snapchat, and TikTok. The schools argue that these platforms were deliberately engineered to be addictive, causing mental and emotional harm to children. They are asking courts to declare the platforms a public nuisance and hold them financially responsible for the costs of managing the fallout—counseling, lost instructional time, resources diverted to address the damage. A jury trial is scheduled to begin in February, though one school district recently settled before trial, which may delay the broader resolution by a couple of years. If the schools prevail, the consequences could be sweeping: changes to how platforms display engagement metrics, who they allow to use their services, and how they design the user experience itself.

The second case involves California and other states suing Meta specifically for violations of the Children's Online Privacy Protection Act, a federal law enacted in 2000 to shield children under thirteen from being targeted by online businesses. Meta has already produced more than two million documents in discovery. If the states win, Meta would be forced to implement stronger barriers preventing users under thirteen from accessing its platforms and to delete data it has already collected from minors. This matters because Meta uses that data for ad targeting and to train its artificial intelligence systems. The company has declined to comment on the case.

The third case centers on a thirteen-year-old boy in San Mateo, California, who claims he was groomed and solicited by an adult predator through both Roblox and Discord. The predator was subsequently arrested for crimes against more than two dozen children. The lawsuit argues that both platforms were defectively designed and made false claims about their safety features, and should therefore be held liable for the harm the boy suffered. Roblox and Discord attempted to move the case into private arbitration, but a court refused. The case is currently on hold while the companies appeal that decision. If they lose their appeals and the case goes to trial, a verdict against them could force changes to age verification systems and the ability of strangers to contact minors through messaging and chat.

The fourth case is different in character but potentially the most consequential. Dr. Andrew Forrest, an Australian billionaire, sued Meta in 2022 over scam advertisements that used his name and likeness to defraud Australians into fake investments. The ads proliferated on Facebook, and Meta profited from them regardless of their legitimacy. Forrest is asking the court to rule that Meta cannot hide behind Section 230 of the Communications Decency Act, a 1996 law that has given online platforms broad immunity from liability for what users post or advertise on their services. If Forrest prevails, it could overturn three decades of legal protection that has shielded platforms from responsibility for content hosted on their sites. Meta has declined to comment.

The outcomes of these cases will not arrive quickly. Even if verdicts come down against the platforms, appeals and further litigation could stretch the process years into the future. But the trajectory is clear. Regulators and lawmakers are watching. The public conversation is shifting. And for the first time, juries are finding that platforms bear responsibility for the harms their design choices have enabled. What comes next—whether it is legislative action, regulatory reform, or a fundamental redesign of how social media operates—will likely depend on how these four cases unfold.
