I've worked in advertising/media buying, at a header-bidding at network that (obligitorily) used DFP/Ad Manager, and an enterprise publisher. Its all true. Their hegemony of ad serving (which isn't free), their bid preference, their rigging of AMP ads, and also search promotion of AMP properties are all extremely real and monopolistic dynamics. I wish this action came sooner.
