Mark Zuckerberg spent years telling America he would never put profits above children's safety.
Now his engineer is sitting in a federal courtroom saying those were lies – told directly to his face.
What this former insider just revealed about Instagram and children is the most damaging testimony Meta has ever faced in court.
Meta Insider Exposes Instagram Child Safety Lies Under Oath
Twenty-nine state attorneys general hauled Meta into federal court in Oakland this week, accusing Mark Zuckerberg of deliberately engineering Facebook and Instagram to hook children – and then lying to the public about what his platforms were doing to them.
The trial opened Tuesday before Judge Yvonne Gonzalez Rogers and is expected to run six weeks.
Arturo Béjar spent years inside Meta building the very safety systems Zuckerberg bragged about publicly.
He briefed Zuckerberg on child safety issues at least 100 times.
Nothing changed.
Under oath in Oakland federal court, Béjar described the company's internal approach to children as a "don't ask, don't tell" policy – management knew underage kids were slipping past safeguards, knew the platforms were pushing sexual predator content and graphic violence onto children's feeds, and deliberately chose to look away.
"You just cannot trust Mark Zuckerberg with kids," Béjar told the jury.
Internal studies documented children encountering content from sexual predators at elevated rates – material landing on the feeds of kids who had no idea it was coming. Béjar brought those findings to Facebook and Instagram executives multiple times.
The response from leadership was silence and inaction.
In 2021, Béjar emailed Zuckerberg directly after the CEO publicly claimed Meta does not prioritize profit over safety.
"I felt that he created a false and misleading impression of Facebook's commitment to young people," Béjar testified.
Béjar watched Zuckerberg's public statements and knew exactly what the Meta CEO had been told behind closed doors. That contradiction is why Béjar is now sitting across the courtroom from his former boss.
Facebook and Instagram Addiction by Design: What Internal Emails Revealed
The company's internal chat logs, now entered into evidence, show Meta employees comparing Instagram to a drug and describing themselves as "basically pushers."
Meta leadership during Béjar's second stint from 2019 to 2021 quietly substituted "problematic use" for "addiction" – a rebranding Béjar testified fell well short of what researchers actually use to define the condition.
The switch was a legal and public relations calculation, not a safety improvement. The product did not change.
Safety metrics Meta put before the public tracked content policy violations – a number that told parents nothing about the actual harm children reported experiencing on the platforms.
California Deputy Attorney General Megan O'Neill called out Meta's business model opening statements: "Hook the user, hold them for as long as they can, harvest their data, and then hide the truth."
She told the jury the younger the child, the more valuable they are to Zuckerberg's machine. "The young ones are the best ones – they are the ones most likely to get hooked, they're the ones that are most likely to make money in the long run."
Meta Child Safety Trial Could Cost Zuckerberg $200 Billion
Meta itself says a loss could cost up to $1.4 trillion – roughly the total value of the company's stock on the Nasdaq. Lawyers for the states told the judge $200 billion is a more realistic number.
This trial does not stand alone. A New Mexico jury already found Meta enabled child predators on its platforms, producing a $375 million verdict and a second-phase order of $567 million into an abatement fund.
A California jury found Meta and YouTube liable in the first individual addiction case to reach verdict and awarded $6 million. The company paid $27 million to settle with a Kentucky school district – alongside Snap, TikTok, and YouTube – rather than face a trial that threatened 1,200 similar lawsuits.
Senator Marsha Blackburn has tracked every step of this fight.
"Meta knowingly put profits ahead of children's safety," she said after the New Mexico verdict. "He knew he was lying," she told the Senate this spring, pointing to Zuckerberg's own 2015 company goal memo listing a 12 percent increase in time spent – even as he told Congress he had no interest in keeping users on the platform longer.
Legal observers are calling this Big Tech's Big Tobacco moment – and the comparison fits. Tobacco companies spent decades lying to the public about what their products did to people.
They paid $200 billion in 1998 when the reckoning finally caught them. Children have been on Instagram for over a decade.
Zuckerberg is expected to take the witness stand himself before the trial concludes. His Instagram chief Adam Mosseri will follow.
The engineer who briefed him 100 times just told a federal jury what he found.
