Presenting Fiction as Fact IS Confusing
From looking at his online profile, I know that Mark is a scientist, trained to be skeptical and not the average reader. Most folks, however, are not so well equipped to deal with a situation where a big, supposedly respectable company presents fiction as fact.
The fact that SO MANY people took SO MUCH time to write books about how SO WRONG the "facts" were in DVC is a measure of how many people were suckered in by the false and deceptive marketing.
It's easy to say they should not be so gullible, but when you're the average person and you've got a BIG NAME like Random House telling you it's TRUE, then you start to trust.
Obviously this sort of trust in Random House is misplaced and should be properly addressed by the class action law suits.
