Inside Zuckerberg’s Defense: How Meta’s Past Moves Are Shaping Its Legal Future

In a courtroom showdown this week, Meta CEO Mark Zuckerberg took the stand to defend the company’s acquisitions of Instagram and WhatsApp amid an antitrust lawsuit filed by the Federal Trade Commission (FTC). The agency accuses Meta of building an unlawful monopoly by purchasing rising competitors. But Zuckerberg’s testimony revealed he saw this kind of legal battle coming years ago—and even floated the idea of spinning off Instagram himself.

Back in 2018, Zuckerberg expressed internal concern that mounting public and political pressure to dismantle big tech could eventually force Meta to separate from Instagram and possibly WhatsApp. In emails presented during the trial, he noted that companies often perform better after being split up, and questioned whether Facebook’s “family of apps” structure might actually weaken its position over time.

Despite his foresight, Meta never carried out a spinoff. Instead, it now finds itself in court fighting to retain its hold on both platforms. Zuckerberg argued that the acquisitions helped improve Instagram and WhatsApp, offering users better products. However, the FTC insists these purchases eliminated potential rivals and cemented Meta’s control over social networking.

Evidence presented during the trial showed that Zuckerberg had been closely monitoring potential threats years before these acquisitions. In 2011, he acknowledged in an email that Instagram had become a formidable player in mobile photography, outpacing Facebook Camera. The following year, Facebook purchased Instagram for $1 billion, citing its rapid growth and the platform's clear competitive edge.

Concerns about WhatsApp were equally pressing. By 2013, Zuckerberg told executives he feared WhatsApp would evolve to directly challenge Facebook and Instagram. Worries also mounted that Google might acquire the messaging platform first. Facebook ultimately secured WhatsApp for $19 billion in 2014, shortly after Zuckerberg met with its co-founder Jan Koum, which reassured him about its strategic fit within Meta.

Zuckerberg didn’t shy away from discussing Facebook’s changing usage trends either. Referencing a 2022 internal report, he confirmed that traditional social behaviors such as making new friends and sharing updates have been on the decline. He pointed out that messaging between individuals or within private groups is now growing faster than public sharing through social feeds.

He also acknowledged Meta’s growing competition, particularly from TikTok and YouTube. He noted that YouTube, with its deep library of video content and influence among younger users, has become the biggest platform for creators. According to Zuckerberg, people are now spending more time on YouTube than on either Facebook or Instagram—an observation backed by Pew Research.

Despite these challenges, Zuckerberg emphasized Meta’s continued dominance in the U.S. social media space. Citing Pew data, he noted that Meta still owns a quarter of the most-used platforms in the country. While user habits and platform preferences are changing, Meta remains a major force—and that’s exactly what the FTC hopes to challenge in this landmark case.
