Just fyi, Google has massive resources devoted to detecting click fraud and getting rid of it. But I agree with the author. While many Google’s engineers and security professionals are focused on providing the most transparency about click fraud, the majority of the company (its business people) have all the incentives to reduce the appearance of click-fraud. If you were holding a spreadsheet that showed how 90% of your budget for self-driving cars, google glass, and other projects, is coming from a ponzi scheme, would you show it to anyone?
