Mark Zuckerberg and his wife, Priscilla Chan, recently acquired a 200-year-old castle valued at approximately €30 million (US$48 million) in Ireland, adding to a growing portfolio of high-value assets that includes a superyacht and a sprawling Hawaii estate. Simultaneously, in California, Deputy Attorney-General Megan O’Neill opened a high-profile trial in Oakland accusing Meta Platforms Inc. of deliberately designing its social media applications to be addictive, significantly impacting the psychological and social wellbeing of young Americans.

Within five days of the trial’s commencement, Meta reached a settlement agreement with 47 attorneys-general, including representatives from California, Colorado, New Jersey, and Kentucky. The $1.5 trillion company agreed to a payment of up to $18 billion over a decade to resolve allegations that it misled the public about the safety of its platforms and intentionally fostered addictive use patterns.

While Meta did not concede any wrongdoing, the settlement requires the company to implement changes targeting teenage users. These include removing “like” counts, enforcing a daily usage limit of two hours, prohibiting night-time access, banning beauty filters, and suspending notifications during school hours. Under the terms, Meta is obligated to pay $12.7 billion immediately, with an additional $5.3 billion contingent upon similar commitments and settlements from competitors YouTube and TikTok.

Consumer advocacy groups welcomed the settlement as a significant victory in regulating social media harms. Jonathan Haidt, author of a notable critique of social media’s effects on youth, underscored the widespread impact these platforms have had on children’s sleep, self-esteem, and attention spans. Wall Street responded positively as well, with Meta’s stock rising 2%, increasing its market capitalization by nearly $30 billion, reflecting relief among investors that the company avoided a much larger $190 billion potential payout.

The settlement highlights an evolving moment for Zuckerberg, once portrayed as an ambitious college student in the 2010 film The Social Network. Since then, his leadership has been subjected to increasing scrutiny amid numerous whistleblower revelations, congressional hearings, and over 2,600 lawsuits in U.S. courts, many involving families attributing their children’s mental health struggles to Meta’s platforms. In a 2024 congressional appearance, Zuckerberg issued a public apology to grieving parents, acknowledging their suffering.

This scrutiny has coincided with Zuckerberg’s pivot towards artificial intelligence. Reports emerged of a radical organizational restructuring called Project OT (Organizational Transformation), aimed at reducing Meta’s workforce dramatically—initially targeting up to a 60% reduction—and replacing many roles with AI-driven automation. Although the deepest cuts were later scaled back to a 10% workforce reduction in May, the initiative reflects Zuckerberg’s broader strategic focus on integrating AI to enhance user engagement, including concepts to address social isolation by creating AI companions.

Meanwhile, Meta’s leadership and Zuckerberg himself have often attracted criticism for ostentatious displays of wealth amid the company’s mounting legal and ethical challenges. Recent acquisitions of luxury properties and a high-priced wristwatch worn at a presidential inauguration have drawn public attention amid ongoing debates about the societal costs of Meta’s platforms.

Key testimony in the attorneys-general’s case came from Arturo Bejar, a former Meta senior safety executive turned whistleblower. Bejar testified that the company prioritized growth and revenue above user safety, especially concerning minors, who represented higher "lifetime value" by the company’s own metrics. Internal communications revealed that Meta placed a monetary value of approximately $350 on each new teenage user, higher than the valuation of older users, underscoring the company’s efforts to attract young audiences.

Despite the settlement, the deal does not resolve the thousands of ongoing lawsuits filed by families affected by mental health crises attributed to social media use. A subset of these “bellwether” cases is scheduled for trial later this year. As Meta navigates this shifting legal landscape, the recent agreement may signal an end to one chapter in Zuckerberg’s stewardship and the beginning of a new, more contested era.
