"Chrome blocker would not block Google Ads because it would classify them as acceptable. And Google would then hope that people would use their built in blocker rather than downloading a third party extension which would highly likely block there ads."

Probably a good call. I've actually suggested they do this before. I doubt it made it to them given it was on a private forum. It's amusing to see it happening, though. It's an extension of monopolistic practices where one blocks out all competition to give their own self an advantage.
