Arturo Béjar’s testimony put Meta’s product decisions and leadership at the center of a landmark Oakland trial. The former Facebook engineering director and safety critic told the court that the company treated child safety as secondary to growth and engagement, while 29 U.S. states accused Meta of designing Facebook and Instagram to keep young users hooked and of misleading the public about the risks.

These are allegations in an ongoing civil case, not final findings. Meta rejects the claim that it intentionally designed its platforms to addict children for profit.

Béjar’s account of Zuckerberg and Meta’s culture
Béjar said Meta employees were heavily focused on user numbers and engagement metrics, while safety and well-being concerns were difficult to turn into product changes. He portrayed Zuckerberg as central to that culture, arguing that decisions with major company-wide consequences ultimately depended on the CEO.

He also accused Meta of ignoring internal research about harms affecting children and teenagers. In Béjar’s description, the company’s approach to underage users resembled a “don’t ask, don’t tell” policy: rather than reliably identifying users younger than 13 and acting on that information, Meta allegedly avoided learning what could trigger additional obligations. That remains testimony from a former employee, not a judicial determination.

Béjar further criticized Meta’s break-reminder tool. His argument was that a prompt users can easily dismiss does little to interrupt compulsive use or change the engagement incentives built into the product. The evidence supplied for this article does not establish the tool’s effectiveness as a legal fact.

The testimony also became personal. Béjar said his teenage daughter received sexual requests and images of private body parts after joining Instagram, an experience he presented as evidence of the harassment risks young users could face on the platform.

What the 29 states allege
The multistate case centers on four connected accusations:
- Habit-forming design: The states allege that Meta deliberately designed Facebook and Instagram to attract young users, keep them engaged and increase advertising revenue.
8
- Safety disclosures: They argue that Meta concealed or downplayed information about the platforms’ risks and misled consumers about youth safety.
8
- Youth mental-health harms: The coalition alleges that Meta’s products contributed to or aggravated harms experienced by young people.
8
- Children’s data: The states also claim that Meta illegally collected and used personal information from children under 13.

Prosecutors have framed the alleged business strategy as “hook” users, “hold” them, “harvest” their data and “hide” the truth from the public.

The product features under scrutiny include infinite scrolling, autoplay, push notifications and personalized recommendation systems—design choices that regulators and plaintiffs say can encourage prolonged or compulsive use.

What Elena Davis’s evidence added
After Béjar’s testimony, jurors heard recorded testimony from Meta researcher Elena Davis. Davis read from research indicating that Facebook could be modified to have “less potential to be habit-forming” and to help users break usage habits they did not want.
The available reporting does not establish the precise intervention Davis proposed, whether Meta adopted it, or what the company’s final response was. The significance of the testimony is narrower but important: it supports the states’ argument that Meta had studied less habit-forming design options, while leaving the legal meaning of that evidence for the court to decide.
Why the trial could change Facebook and Instagram
The eight-person jury is serving in an advisory role rather than issuing the final binding decision. Judge Yvonne Gonzalez Rogers will determine whether Meta is liable and, if so, whether to impose civil penalties or order changes to Facebook and Instagram.

The states are seeking remedies that could affect core product features, including changes involving visible “like” counts and infinite scroll. A ruling against Meta could also influence thousands of related youth-harm lawsuits and increase pressure for broader safety redesigns, although the eventual penalties and scope of any injunction cannot be known while the case is pending.

The central question is therefore larger than whether one former employee’s account is persuasive. It is whether engagement-driven design, internal knowledge of youth risks and public safety assurances together amount to a legal violation—and what responsibilities a platform should have when its most valuable users are also among its most vulnerable.
