The Chief Executive Officer of Meta, Mark Zuckerberg, appeared in a Los Angeles court this week to answer questions about the safety of his social media apps. This trial is a major event because it involves over 1,600 families who claim that platforms like Instagram caused their children to suffer from depression and other health problems. The legal outcome could change how all tech companies are held responsible for what happens to their users. During his testimony, Zuckerberg defended his company’s actions, while lawyers for the families used internal company emails to argue that the platform was designed to be hard to put down. The stakes are high for the tech industry, as a loss for Meta could lead to many more lawsuits across the country.
Chronology and Key Participants
The trial focuses on whether Meta knowingly created a product that harms young people. This case is being watched closely as countries like Australia and Spain move toward banning or strictly limiting social media for children.

Location: Los Angeles County Court.
Main Actor: Mark Zuckerberg, CEO of Meta.
Legal Representative for Plaintiffs: Mark Lanier, a lawyer representing families.
The Litigants: Families of approximately 1,600 children alleging harm from app usage.
Key Event: A full day of testimony where Zuckerberg was questioned about internal emails, age checks, and his past statements to the government.
"I think a reasonable company should try to help the people that use its services." — Mark Zuckerberg during court testimony.
Evidence and Testimony Data
| Category | Evidence Presented | Zuckerberg's Response |
|---|---|---|
| User Engagement | Internal emails discussing goals for time spent on the app. | Claims the company moved away from "time spent" goals to focus on "utility." |
| Expert Advice | Reports from 18 mental health experts warning about beauty filters. | Stated the experts did not present data he found "compelling." |
| Age Limits | Evidence of children under 13 using the platform. | Stated the company has a ban on under-13s, but some users lie about their age. |
| Corporate Intent | Internal slide decks showing focus on "authentic" behavior. | Argued he did not want to be "paternalistic" or "overbearing" in limiting expression. |
The core of the trial rests on whether Meta prioritizes the health of young users or the amount of time they spend on the apps.
Analysis of Conflict: Business Goals vs. Safety
App Design and Time Spent
Lawyers for the families claimed that Meta designs its apps to keep users scrolling for as long as possible. They argued that this "addictive" design is a choice made to make more money.

Zuckerberg testified that while the company used to track how much time people spent on the app, they chose to stop.
He explained that the company now focuses on how useful the app is for connecting people.
If the company no longer uses "time spent" as a goal, why is it still used to compare Meta against competitors like TikTok?
Expert Warnings on Beauty Filters
Evidence was shown that 18 mental health experts warned Meta that certain beauty filters could be harmful to the self-image of teenage girls.
Zuckerberg stated he chose not to ban these filters because he did not want to tell people how they should express themselves.
He also mentioned that the research provided by the experts was not strong enough to force a change.
Did the company prioritize "free expression" over the health warnings of experts, or was the research truly not strong enough to act on?
Protecting Children Under 13
The court discussed how easy it is for children under the age of 13 to join Instagram despite the company's rules.

Zuckerberg maintained that children under 13 have never been allowed on the platform.
He acknowledged that some children lie about their age to get around the rules.
Lawyers questioned if the company's age verification is strong enough to keep children safe.
Is it possible for a large tech company to accurately verify the age of every user, or are the current systems intentionally easy to bypass?
Expert Observations
Industry watchers and children’s advocates have closely followed the testimony. Many advocates described the CEO's answers as "disingenuous," suggesting he was not being fully honest about how the apps work. On the other hand, legal experts noted that Zuckerberg remained calm and often pointed out that he was not part of many of the email chains shown as evidence.
Meta continues to use a report from the National Academies of Sciences to support their side. This report states that research does not clearly prove that social media causes changes in the mental health of children. This creates a gap between the personal experiences of the 1,600 families and the scientific data the company chooses to follow.

Summary of Findings
The trial has highlighted a significant disagreement between how Meta views its responsibilities and how families experience its products. Zuckerberg claims the company is a tool for connection that tries to help its users. The families argue that the apps are designed to be addictive and that their warnings were ignored.

Key Points:
Meta denies using "addiction" as a business model but admits to tracking time spent as a performance measure.
Zuckerberg defended his decision to keep beauty filters by citing a desire not to be "paternalistic."
The trial will determine if Meta is legally responsible for the mental health of its younger users.
The next steps in the trial will involve more testimony from experts and former employees. If the court finds against Meta, it could lead to new laws and many more lawsuits for the entire tech industry.
