The FTC’s economic expert Scott Hemphill is back on the stand testifying about how Meta’s alleged monopoly power allows it to offer different prices to different users and across its services. For example, Meta didn’t show ads on Reels for a while, but it did show ads in other parts of the Instagram app. Hemphill compares this to what sounds like the antitrust case against Whole Foods — saying that a supermarket specializing in premium, natural foods might have high margins on its organic mangos, but low margins in areas on which it competes with many other stores, like pantry staples. He says this is similar to Meta lowering prices on the product where it competes with other apps (short-form videos) but not on the one where it dominates the market (friends and family sharing on Feed and Stories).
