How is that you imagine that "these people" don't have full control over any data and the entire process?

I genuinely would like to know how it even happens that you think you know better.

Then, data transparency is a thing and advertisers can obviously also measure their performance.

The point is, I don't know better --- and neither do you.

For example, you and I have no idea if the ad networks are bidding against their own advertisers in order to drive revenue. They hold all the cards.

Ad fraud is a growing business and ad networks are not the ones getting hurt directly by it.
