Overview

• Adam Mosseri testified that TikTok is Instagram's fiercest competitor, attributing 40% of user engagement declines, including 23% in the U.S., to the app.
• Meta has invested 'hundreds of millions, maybe a billion or two,' in creator incentives and infrastructure to counter competition from TikTok and similar platforms.
• Mosseri acknowledged early missteps with Instagram's Reels feature, which was relaunched as a standalone product to better compete with TikTok.
• Internal emails revealed Mosseri's 2018 concerns over Instagram's 'woefully understaffed' safety teams, which he argued needed more resources to address content safety effectively.
• The FTC aims to prove Meta's acquisitions of Instagram and WhatsApp created an illegal monopoly, seeking divestiture of both platforms in a case that could reshape Big Tech antitrust enforcement.
