Mark Zuckerberg has sparred with lawyers in a Los Angeles courtroom as he defended Meta’s practices in an unprecedented trial over youth social media addiction.

Meta chief executive Mark Zuckerberg has repeatedly said the Facebook and Instagram operator doesnât allow kids under 13 on its platforms, during a landmark trial over youth social âmedia addiction.
Mark Lanier, a lawyer for a woman suing Instagram and Googleâs âYouTube for harming her mental health when she was a child, pressed Zuckerberg over his statement to Congress in 2024 that users under 13 are not allowed on the platform.
Lanier confronted Zuckerberg with internal Meta documents.
âIf we want to win big with teens, we must bring them in as tweens,â read one internal Instagram presentation from 2018.
âAnd yet you say that we would never do that,â said Lanier.
Zuckerberg replied that Lanier was âmischaracterising what I am sayingâ.
The âchief executive said Meta has âhad âdifferent conversations over time to try to â build different versions of services that kids can safely useâ.
For example, he said Meta discussed creating a version of Instagram for children âunder 13, but ultimately never did.
Also presented was an email in which Nick Clegg, who was Metaâs vice president of global affairs, told Zuckerberg and other top executives, âwe have age limits which are unenforced (unenforceable?)â and noted different policies for Instagram versus Facebook make it âdifficult to claim we are doing all we canâ.
Zuckerberg responded by saying it is hard for â app developers to verify user age and the responsibility should be on the makers of mobile devices.
Earlier in his questioning, Lanier laid out three options of what people can do regarding vulnerable people: help them, ignore them, or âprey upon them and use them for our own endsâ.
Zuckerberg said he agrees the last option is not what a reasonable company should do, saying, âI think a reasonable company should try to help the people that use its servicesâ.
When asked about his compensation, Zuckerberg said he has pledged to give âalmost allâ of his money to charity, focusing on scientific research.
Lanier asked him how much money he has pledged to victims impacted by social media, to which Zuckerberg replied, âI disagree with the characterisation of your questionâ.
Lanier also asked Zuckerberg about his âextensiveâ media training, and pointed to an internal document about feedback on Zuckerbergâs tone of voice on his own social media, imploring him to come off as âauthentic, direct, human, insightful and realâ, and instructing him to ânot try hard, fake, robotic, corporate or cheesyâ in his communication.
Zuckerberg pushed back against the idea that heâs been coached on how to respond to questions, saying those offering the advice were âjust giving feedbackâ.
Regarding his media appearances and public speaking, Zuckerberg said, âI think Iâm actually well known to be sort of bad at this.â
Zuckerberg also faced âquestions about his statement âto Congress that he did not give Instagram teams the goal of maximising time spent on the app.
Lanier showed jurors emails from 2014 and 2015 in which Zuckerberg laid out aims to increase time spent on âthe app by double-digit percentage âpoints.
Zuckerberg said while Meta previously had goals related to the amount of time users spent on the app, it has since changed its approach.
âIf you are trying to say my testimony âwas not accurate, I strongly disagree with that,â Zuckerberg said.
The appearance was the billionaire Facebook founderâs first time testifying in court on Instagramâs effect on the mental health of young users.
Adam Mosseri, head of Instagram, testified last week he was unaware of a recent Meta study showing no link between parental supervision and teensâ attentiveness to their own social media use.
Metaâs lawyer âtold jurors at the trial the womanâs health records show her issues stem from a troubled childhood, and that social media was a creative outlet for her.
