It'd probably be a PITA just to customize all the different ad blocks for a site like CNN's - many are template pages, but they have lots of different templates and ad spots. I can barely keep up with the different ad blocks (and channels) for my own sites as it is.
A lot of webmasters assume that people hate ads or will love to install those ad blocking toolbars. The reality is that people hate those intrusive popup ads or those banner ads flashing but in reality when people are ready to buy a digital camera,for example, they want to see ads from people who will sell it to them at a good price. If those ads are served by Google or not is not the point.
