In a San Francisco federal courtroom, the head of Instagram acknowledged this week that a tool designed to protect teenagers from compulsive use had reached fewer than two percent of young accounts before the company quietly made it mandatory — nearly three years after its launch. The admission arrived at the center of a $200 billion lawsuit brought by 29 American states, which argue that Meta knowingly engineered its platforms to capture and hold the attention of children at the expense of their mental health.

Instagram Chief Admits Few Teens Used Safety Feature Before Default Activation
Alleged mental health harms to young users including anxiety, depression, and suicide linked to platform design.
Most teens didn't want it. We decided to push forward with it anyway.
Mark
Why does it matter that only 1 or 2 percent of teens were using Take a Break before it became mandatory?
Mimi
Because it shows the company knew the feature existed, knew it worked for people who used it, but didn't make it standard. If you truly believed something was good for young people, you'd turn it on by default. The fact that they didn't—for three years—suggests they were choosing engagement over safety.
Mark
But couldn't Meta argue that they were respecting teen autonomy by letting them choose?
Mimi
That's what they might say, but the testimony from their own employees contradicts it. These weren't features hidden because they were experimental or unproven. They were hidden because making them default would reduce how much time kids spent on the app, and that directly affects ad revenue.
Mark
So the company knew the tools worked but didn't deploy them?
Mimi
Exactly. Mosseri even said it plainly: most teens didn't want the feature, so they pushed it anyway—but only after the states sued them. That's not a company prioritizing youth wellbeing. That's a company responding to legal pressure.
Mark
What does this mean for the broader case?
Mimi
It establishes a pattern. If Meta had other opportunities to reduce harm and didn't take them until forced, it suggests the platform's design choices were deliberate. The judge will have to decide if that amounts to negligence or something worse.
Mark
Could Meta win despite this testimony?
Mimi
Possibly. They'd argue correlation isn't causation—that social media didn't cause the mental health crisis, it just exists alongside it. But Mosseri's admission makes that harder to sell. You can't claim you care about teen mental health while keeping safety features off by default.
El Pulso
- Instagram's own chief conceded that a safety feature celebrated for its effectiveness had been quietly left optional for years, reaching only 1 to 2 percent of teenage users before being made default in 2024.
- Former Meta engineers testified that safety tools were deliberately buried and that activating them by default was rejected because it would visibly damage the engagement numbers that fuel advertising revenue.
- Twenty-nine US states are pressing a $200 billion lawsuit alleging Meta engineered addiction into its platforms while misleading the public, with four states further charging deliberate targeting of minors and illegal data collection.
- Meta insists its own research shows no proven causal link between its platforms and adolescent mental health decline, framing the lawsuit as an overreach built on contested science.
- With six weeks of trial ahead and a federal judge set to rule on liability and potential penalties, the verdict could either force a structural reckoning across the social media industry or shield it from future accountability.
In a San Francisco federal courtroom, the head of Instagram acknowledged this week that a tool designed to protect teenagers from compulsive use had reached fewer than two percent of young accounts before the company quietly made it mandatory — nearly three years after its launch. The admission arrived at the center of a $200 billion lawsuit brought by 29 American states, which argue that Meta knowingly engineered its platforms to capture and hold the attention of children at the expense of their mental health. It is a moment that asks an old question in a new register: when a company understands the harm it causes and chooses profit over prevention, where does responsibility end and accountability begin?
On Tuesday, Instagram chief Adam Mosseri took the stand in a federal courthouse where Meta confronts its gravest legal challenge — a $200 billion lawsuit filed by 29 US states alleging that Instagram and Facebook were deliberately built to addict young people, whatever the cost to their wellbeing.
The testimony turned on a single feature called Take a Break, which prompts teenagers to step away from the app after extended use. Mosseri had publicly boasted in 2021 that more than 90 percent of teens who activated it kept it on. But when pressed by Colorado's attorney, he acknowledged the figure that had never been disclosed: before Instagram made the feature a default setting in September 2024, only 1 or 2 percent of teenage accounts had ever turned it on. Asked why the company waited nearly three years to act, Mosseri offered a candid answer — most teens didn't want it, and Meta pushed forward anyway.
Former employees filled in the rest of the picture. Engineering director Arturo Bejar, who left the company, told the court the feature was designed to fail. Data scientist George Volichenko testified that leadership had explicitly blocked making Quiet Mode — a notification-limiting tool — a default for young users, citing the measurable hit it would take on engagement metrics.
The lawsuit is sweeping in its ambitions. Four states accuse Meta of deliberately engineering addiction while driving up rates of anxiety, depression, and suicide among young users. All 29 allege violations of federal law through the collection of children's data without parental consent. Meta denies the charges, arguing its research shows no clear causal link between its platforms and adolescent mental health harm.
US District Judge Yvonne Gonzalez Rogers will ultimately decide whether Meta is liable and what penalties or operational changes may follow. The trial, now in its second week with six more expected, carries stakes that extend well beyond this courtroom — its outcome may define what social media companies owe the young people they are built to keep.
Adam Mosseri took the stand on Tuesday in a federal courthouse where Meta faces its most serious legal test yet—a $200 billion lawsuit brought by 29 US states alleging that Instagram and Facebook were deliberately engineered to addict young people, regardless of the mental health consequences. The Instagram chief's testimony cut to the heart of the case: a safety feature designed to combat excessive use had barely been adopted by teenagers before the company made it mandatory.
The feature in question, called Take a Break, prompts teenage users to close the app after spending a certain amount of time on it. Mosseri had written in a blog post in December 2021 that more than 90 percent of teenagers who activated the feature kept it turned on. But that statistic masked a critical gap. When pressed by Colorado's lawyer, Jason Slothouber, Mosseri acknowledged that before Instagram made Take a Break the default setting in September 2024—nearly three years after launching it—only 1 or 2 percent of teenage accounts had the feature enabled at all. The company had not publicly disclosed this low adoption rate.
When asked why the feature remained optional for so long despite its poor uptake, Mosseri's answer was blunt: "Most teens didn't want it. We decided to push forward with it anyway." The admission seemed to confirm what the states suing Meta have argued throughout the trial—that the company knew its safety tools were unpopular and chose not to make them standard because doing so would interfere with engagement metrics that drive advertising revenue.
This narrative has been reinforced by testimony from former Meta employees who worked on these very features. Arturo Bejar, an engineering director who left the company, told the court last week that Take a Break was "a feature that's designed to fail." George Volichenko, a data scientist who worked on Instagram's safety features in 2022 and 2023, testified on Monday that adoption rates for such tools were consistently "very low" and that company leadership had explicitly rejected making Quiet Mode—another feature meant to limit notifications—a default setting for young teenagers. His reason: doing so would have a "notable negative impact" on user engagement.
The lawsuit itself is unprecedented in scope. Four states—California, Colorado, Kentucky, and New Jersey—have accused Meta of deliberately designing its platforms to hook young users, driving increases in anxiety, depression, and suicide while misleading the public about safety. All 29 states also allege that Meta violated federal law by collecting and using personal data from children under 13 without proper consent. Meta has denied these charges, arguing that its own research shows no clear causal link between social media use and adolescent mental health problems.
Mosseri's testimony came as the trial entered its second week, with six weeks of proceedings expected. The case will ultimately be decided by US District Judge Yvonne Gonzalez Rogers, who will determine whether Meta is liable and, if so, what civil penalties and operational changes the company must face. The verdict, when it comes, could reshape how social media companies approach youth safety—or it could set a precedent that protects them from similar suits. For now, the evidence being presented suggests that Meta knew its safety features worked but chose not to use them as defaults because doing so would cost the company money.
