> No, ad buyers are businesses. As much as business interests have been trying to redefine negative impact on consumers as including out-competing rival companies, that’s not what it means. That's a bit of a non sequitur. Ad-buying businesses aren't, generally, rivals to the ad-selling platform. It isn't necessarily a bad model to treat them as consumers, or at least as proxies for actual consumers. The cost of monopoly rents being passed on to consumers isn't a particularly controversial proposition.
