To me that looks like an actual antitrust violation but the DoJ and FTC aren’t investigating bc they are obsessing about “big tech” uselessly and bringing bad cases they are going to lose!
If you want your regulators to actually do something about a lack of competition in the US economy (which they really should be doing!) there are a ton of markets worth investigating before they waste their time on this loser of a case.
It's also a lot better than the ads market is, with literally one dominant player that monopolizes all stages of the supply chain. This is literally what Standard Oil did, controlling the wells, the refineries, and the distribution railroads to shut out competitors.
If you look at financial exchanges, there's a very good reason for the brokers and exchange to all be different companies.
But, hey, maybe you’re right. Maybe it’s a bad case being done for show. Slap on the wrist, back to business as usual sort of deal.
