Did Google help bootleggers?

Google was accused of working with a couple websites known for providing users bootleg copies of movies.  Ars Technica has a good article describing the events leading up to the accusation, and it also explains that Google has not been threatened with any sort of legal action.

According to sworn statements from the two men, Google reportedly noticed the amount of traffic and advertising served by the two web sites and assigned them an account representative to help optimize their efforts. This has been construed by the media companies as a collusive act, but is it?
