This sort of ad-hominem attack doesn't really have a place on Hacker News. It's no secret that Scott Cleland is an anti-Google shill, available for hire by fortune 500 companies to write books and testify in front of Congress, but the correct response to his arguments is to point out the gaps in his reasoning and prove him wrong.
Instead, this is an appeal to groupthink to disregard the fair (and not-so-fair) questions raised in the blog post, instead of responding critically to them.
