Kevin Systrom’s Critique of Mark Zuckerberg in FTC Antitrust Case
Instagram co-founder Kevin Systrom offered a critical view of Meta’s CEO, Mark Zuckerberg, during his testimony regarding the federal antitrust lawsuit aimed at dismantling Meta. He alleged that Zuckerberg intentionally suppressed Instagram’s growth to safeguard Facebook’s interests.
On Tuesday, from a courtroom in Washington, D.C., Systrom discussed how Instagram, despite amassing billions of users and generating significant revenue since its acquisition for $1 billion in 2012, faced continuous obstruction due to Zuckerberg’s interventions.
“Instagram posed a threat to their expansion,” Systrom declared during his testimony. “If Instagram’s growth was slowed down, Facebook’s decline or stagnation would also be delayed.”
This testimony comes as the FTC seeks to reverse Meta’s purchases of both Instagram and WhatsApp. Systrom suggested that Zuckerberg’s strategy involved withholding essential resources from Instagram, such as engineering expertise and integration capabilities, intending to prevent Facebook from losing user engagement.
Systrom recounted that just prior to his and co-founder Mike Krieger’s resignation in 2018, Zuckerberg withdrew support for significant features that could boost Instagram’s visibility on Facebook. The internal reasoning, as Systrom described it, was to dampen Instagram’s ascent at the cost of Facebook’s growth.
“He appreciated having Instagram within the company,” Systrom remarked. “Yet, as Facebook’s founder, he harboured strong feelings regarding which platform was superior… There were definitely genuine emotional factors involved.”
In a notable instance, Systrom disclosed that during Facebook’s significant shift towards video, Zuckerberg assigned 300 employees to this initiative at Facebook while Instagram received none. Even following the Cambridge Analytica crisis, when Meta pledged billions to enhance user safety, Systrom stated that Instagram did not benefit from any of those funds directly.
During cross-examination, Meta’s lawyer, Kevin Huff, contested Systrom’s assertions by presenting an earlier email in which Systrom acknowledged Facebook’s contributions to Instagram’s growth. When asked if he had deceived Zuckerberg in that email, Systrom’s reply was curt: “Sir.”
Systrom’s testimony follows Zuckerberg’s, who testified the previous week that Instagram’s achievements depended heavily on Meta’s infrastructure. These differing perspectives now lie at the heart of the FTC’s efforts to demonstrate that Meta retained its market supremacy through anti-competitive behaviours rather than through superiority.
As the trial progresses, it reveals an exceptional insight into the friction between two of Silicon Valley’s most influential leaders—and the future of Meta’s empire might depend on which narrative the court accepts.
