Twitter’s (X) Nikita Bier Defends Zuckerberg After Meta Whistleblower Trailer

X head of product Nikita Bier publicly defended Mark Zuckerberg over the new trailer for The Social Reckoning. The film portrays Meta as a company that ignored teen mental health.

The Aaron Sorkin sequel to The Social Network is set to hit theaters this fall. Its first trailer suggests Facebook fueled anxiety and depression among teenage users.

A Sequel Built Around the Facebook Files

Sony released the trailer this week. The sequel follows a whistleblower who leaks internal company research to the press. The story tracks how those revelations reached regulators and intensified public scrutiny of the platform.

The film dramatizes the Facebook Files, the 2021 investigation built on leaked documents. That reporting showed Meta knew its platforms could harm teen mental health and deepen political polarization. The whistleblower at the center of the case later testified before the US Senate.

The trailer frames the company as one that chose growth over user safety. It leans on internal research and congressional hearings to build that case.

Early reactions online suggest the marketing push has already revived old criticism of Meta.

Meanwhile, the timing adds pressure on Meta. The company is already contending with declining employee morale following this year’s tech layoffs. It is also funding a capital-heavy AI data center project with Reliance in India.

Bier Defends Zuckerberg’s Teen Safety Record

Bier pushed back against the trailer’s premise on X. He speaks from experience, as Meta acquired his teen-focused app, tbh, in 2017. He later worked there as a product manager before joining X in July 2025. His career has centered on consumer apps built for young users.

He made the argument in a post responding to the trailer.

“He makes a lot of mistakes, but this isn’t one of them.”

According to Bier, Meta employed multiple engineering teams earning $1 million a year with one mission: protecting teen mental health. He added that those groups held real authority to override major product choices inside the company.

Meta’s Record Faces Its Own Scrutiny

Bier frequently weighs in on platform decisions in public. At X, he has teased crypto features and weathered content suppression accusations from frustrated users. He also shared snooze data showing users mute crypto more than politics.

However, Meta’s record on teen safety continues to face legal and political scrutiny in several US states. The company points to its teen accounts and expanded parental controls in response.

Therefore, the clash now pits a prominent Silicon Valley product leader against Hollywood’s account of Meta’s history. The debate over which version holds up will likely intensify once the film hits theaters this fall.
