"The darker consequence is that this will entrench Meta’s market domination. Exclusive knowledge of which ad works best across millions of campaigns gives it a unique advantage over rivals like Alphabet Inc.’s Google, TikTok and traditional agencies. And while the obvious first users will be small businesses, there’s no reason why larger ones might not want to reduce their ad-agency spending for Meta’s tools if they’re cheap and effective.
Of course, measuring “effectiveness” means trusting Meta’s metrics, per Zuckerberg’s you-don’t-need-any-measurement just “the results that we spit out.” That is a little bit like trusting a casino that deals the cards and runs the tables to tell you how well you’re doing. It’s a convenient closed loop for Meta. With no independent verification, the company could optimize ads to boost user engagement and benefit its platform rather than for advertiser success, and brands would struggle to know if that’s the case or not."
