In Los Angeles, a critical legal battle has commenced, with attorney Mark Lanier likening social media platforms to casinos and addictive substances during his opening statements. This trial seeks to hold Instagram’s parent company, Meta, and Google’s YouTube accountable for the alleged harm their platforms inflict on young users.
The crux of the lawsuit contends that these tech giants have intentionally crafted their platforms to captivate children, effectively fostering addiction. Initially, the lawsuit included TikTok and Snap, but both entities opted to settle for undisclosed amounts.
As the trial unfolds, jurors are set to navigate a complex landscape of contrasting arguments presented by the plaintiffs and the defense teams of Meta and Google. The courtroom will become the stage for a heated debate over the responsibility these companies bear for the purported impact of their services on children.
Meta’s legal representative, Paul Schmidt, highlighted the existing divide among scientists regarding the concept of social media addiction. He noted that some experts question whether such addiction truly exists, or if “addiction” is even the right term to describe the intense usage of these platforms.
On the schedule for Tuesday, YouTube’s legal team will present their opening arguments, further adding to the discourse on the implications of social media use among the youth.
‘Addicting the brains of children’
Mark Lanier, advocating for the plaintiffs, delivered an animated introduction, simplifying the case as “easy as ABC,” which he defined as “addicting the brains of children.” He accused Meta and Google, two of the most affluent companies globally, of deliberately engineering addictive experiences for young users’ minds.
He presented jurors with a slew of internal emails, documents and studies conducted by Meta and YouTube, as well as YouTube’s parent company, Google. He emphasized the findings of a study Meta conducted called “Project Myst” in which they surveyed 1,000 teens and their parents about their social media use. The two major findings, Lanier said, were that Meta knew children who experienced “adverse events” like trauma and stress were particularly vulnerable for addiction; and that parental supervision and controls made little impact.
He also highlighted internal Google documents that likened some company products to a casino, and internal communication between Meta employees in which one person said Instagram is “like a drug” and they are “basically pushers.”
At the core of the Los Angeles case is a 20-year-old identified only by the initials “KGM,” whose case could determine how thousands of other, similar lawsuits against social media companies will play out. She and two other plaintiffs have been selected for bellwether trials – essentially test cases for both sides to see how their arguments play out before a jury.
Plaintiff grew up using YouTube, Instagram
KGM made a brief appearance after a break during Lanier’s statement and she will return to testify later in the trial. Lanier spent time describing KGM’s childhood, focusing particularly on what her personality was like before she began using social media. She started using YouTube at age 6 and Instagram at age 9, Lanier said. Before she graduated elementary school, she had posted 284 videos on YouTube.
The outcome of the trial could have profound effects on the companies’ businesses and how they will handle children using their platforms.
Lanier said the companies’ lawyers will “try to blame the little girl and her parents for the trap they built,” referencing the plaintiff. She was a minor when she said she became addicted to social media, which she claims had a detrimental impact on her mental health.
Lanier said that despite the public position of Meta and YouTube being that they work to protect children, their internal documents show an entirely different position, with explicit references to young children being listed as their target audiences.
The attorney also drew comparisons between the social media companies and tobacco firms, citing internal communication between Meta employees who were concerned about the company’s lack of proactive action about the potential harm their platforms can have on children and teens.
“For a teenager, social validation is survival,” Lanier said. The defendants “engineered a feature that caters to a minor’s craving for social validation,” he added, speaking about “like” buttons and similar features.
Meta pushes back
In his opening statement representing Meta, Schmidt said the core question in the case is whether the platforms were a substantial factor in KGM’s mental health struggles. He spent much of his time going through the plaintiff’s health records, emphasizing that she had experienced many difficult circumstances in her childhood, including emotional abuse, body image issues and bullying.
Schmidt presented a clip from a video deposition from one of KGM’s mental health providers, Dr. Thomas Suberman, who said social media was “not the through-line of what I recall being her main issues,” adding that her struggles seemed to largely stem from interpersonal conflicts and relationships. He painted a picture – with KGM’s own text messages and testimony pointing to a volatile home life – of a particularly troubled relationship with her mother.
Schmidt acknowledged that many mental health professionals do believe social media addiction can exist, but said three of KGM’s providers – all of whom believe in the form of addiction – have never diagnosed her with it, or treated her for it.
Schmidt emphasized to the jurors that the case is not about whether social media is a good thing or whether teens spend too much time on their phones or whether the jurors like or dislike Meta, but whether social media was a substantial factor in KGM’s mental health struggles.
A reckoning for social media and youth harms
A slew of trials beginning this year seek to hold social media companies responsible for harming children’s mental well-being. Executives, including Meta CEO Mark Zuckerberg, are expected to testify at the Los Angeles trial, which will last six to eight weeks. Experts have drawn similarities to the Big Tobacco trials that led to a 1998 settlement requiring cigarette companies to pay billions in health care costs and restrict marketing targeting minors.
A separate trial in New Mexico, meanwhile, also kicked off with opening statements on Monday. In that trial, Meta is accused of failing to protect young users from sexual exploitation, following an undercover online investigation. Attorney General Raúl Torrez in late 2023 sued Meta and Zuckerberg, who was later dropped from the suit.
A federal bellwether trial beginning in June in Oakland, California, will be the first to represent school districts that have sued social media platforms over harms to children.
In addition, more than 40 state attorneys general have filed lawsuits against Meta, claiming it is harming young people and contributing to the youth mental health crisis by deliberately designing features on Instagram and Facebook that addict children to its platforms. The majority of cases filed their lawsuits in federal court, but some sued in their respective states.
TikTok also faces similar lawsuits in more than a dozen states.
