Google is illegally monopolizing online advertising tech, judge rules

I don't think this article explains it well. Google sells ad space on behalf of the publishers and also sells the ads on behalf of the advertisers. It also runs the auction that places the ads into the ad space. See this graphic https://images.app.goo.gl/ADx5xrAnWNicgoFu7. Parts of this can definately be broken up without destroying Google.

When a media buyer puts $1.00 in on one side of the system, on average only $0.60 makes it to the publisher. In some cases less than $0.50 gets to them.

Advertising is an intentionally complex system so that companies can clip the ticket at multiple stages throughout the process. Google should be broken up, but the whole ad tech system needs to go into the bin if these problems are going to ever get fixed.

The argument here being that the fee is too high? I don't think prices being too high is a strong argument of the existence of a monopoly, but it might be of the exploitation of one.
