Good for them to block AdSense ... Google has had a free ride on the backs of webmasters and carriers for too long. The premise of a ''cut'' of the action sucks however. The Mobile carriers are greedy fucks in that aspect.
Maybe one day: Webmasters will charge Google for the rights to use the webmaster's content in the SERPs so they can sell their AdWords. An Interweb Google Tax
The Web just has to have the balls to block Googlebot for 90 days (one quarter and crash Google's stock) -- it will never happen so long as some get to chew on the bones that Goggle tosses its ''dogs.''
