He covers the motivation for this in the book (as well as other departures from traditions of not talking about things he considers important to talk about). Basically there's a tradition of people keeping people in the dark about things that he thinks does more harm than good. I'm not qualified to comment on the wisdom of either approach, just pointing out that it's covered in the first part of the book, and other parts, e.g. "Mushroom Factor".
