The basic premise of the article is false, Google is a publicly-traded company that fully discloses its financial statements and the results are audited by Certified Public Accountants. Their financials prove the articles premise as incorrect.
Furthermore, if you read the article you would have noticed that the author was bitter about Google banning one of his clients from the AdWords program. This is a typical response from an account stakeholder who got himself or his client banned from the program. Google provides setting options and reports that allow you to see and control the keyword targeting at any level you wish. The author seems oblivious to the tools and reports that are available to him from within the account. Instead of using this as a learning moment to improve his knowledge he chose to accuse Google of malice. It’s just a sad situation for the author. Nothing of value for warriors.
