If you look at his profile he gives his real name and his company and he clearly stands behind and owns his comments. You seem to be pushing "Cluetrain" as some form of political correctness. At some point a company becomes more than a collection of startup founders, which it must to succeed, and makes commitments as a firm based on a working consensus. I don't find it hard to believe that the founders talked over what books had been most useful: for me the "we" sounds natural now hollow.
