When you sell ad space, you have to use a Google program to broker that deal for you. When you buy ad space, you have to use a Google program to broker that deal for you. And the market these deals are brokered on is also Google's.
In an ideal world, the brokers buying and selling ad space should be trying to get the best deal for their customers. But when Google runs all sides of the table, it's optimizing for it's own profit.
And, yes, the world would be a better place if markets with a network monopoly were subject to compulsory routing rules (like reg NMS) and anti-fraud rules (like 10b-5).
Compulsory routing should kick in after a reasonable run of first-mover monopoly profits, balancing the need to incentivize investment against the need to limit rent seeking.
