Mark Zuckerberg's emails from over a decade ago reveal his pre-existing antitrust concerns, which are now central to the FTC's case against Meta. During his testimony, Zuckerberg's emails highlighted his anxieties about competitors like Instagram and WhatsApp, even predicting the potential benefits of a Meta breakup. The FTC presented emails showing Zuckerberg's concerns about these companies' growth and their potential to rival Facebook. The trial, featuring Zuckerberg and Sheryl Sandberg as initial witnesses, is expected to last eight weeks. Meta's defense argues Zuckerberg's worries were typical in Silicon Valley, while the FTC aims to prove Meta's acquisitions cemented its monopoly.
