In most of the cases JUST SHOWING the ad is enough to get revenue. Publishers that don't understand how it works are more likely to make less.
Forcing ads on people who don't want to see them may benefit publishers in the short term, but it will not benefit the advertisers themselves, and they will be looking at the relationship between advertising spend and sales.
Advertisers prefer to spend where there is a return on their investment, and they will not continue with publications that under-perform.
