adsense publishers are not suppliers ..they are providing venues for the automatic display of ads to viewers, these ads are paid for by adwords customers and are supplied automatically to these "venues" by Google..
Think they are screwing with you ? ..maybe they are..or not ..but if you are really unhappy with Google and think that they are keeping extra money back for themselves..take the adsense code off your pages..
You don't let them control your inventory..you have no "inventory" ..you merely put up a billboard on a subject ..with content..you let them stick ads in the spaces on it ..and they give you a cut of what they get from the advertisers..think they are cheating you ? ..they are not the only ad network ..you can even sell access to your space and the eyeballs it attracts, you can do this direct with advertisers..( but it is more work..although it pays better ;-) many of us do ..and run adsense too , sometimes on the same pages and sites..
