Meta pushed back with a much broader map of competition. The company’s lawyers argued the FTC had airbrushed out the apps users actually bounce between — rivals such as TikTok, YouTube, Snapchat, Apple $AAPL’s iMessage, and others — and that attention, not friend lists, defines today’s real market. Boasberg ultimately agreed that leaving out TikTok and YouTube broke the agency’s theory, writing that adding TikTok alone was enough to sink the case. In his opinion, he even reached for Greek philosopher Heraclitus, noting that the social media “river” the FTC sued over has “changed markedly” since 2020.
