Given your repeated complaints about people not knowing what this book is about, I have absolutely no clue how you're coming to this conclusion. The info we have so far has made it very clear that the authors' intentions are to be the "anti-Moneyball." They think the Moneyball approach is a flawed and "doomed" one (and are somehow showing this with the Red Sox, of all teams). If their goal is what you've stated, then they're still writing a stupid book because Moneyball is hardly the source to base such an argument around. Contrary to what certain people think, MB is not some kind of sabermetric bible. In short, there's absolutely no way the book is as measured and sensible as you're stating, that's abundantly clear from the authors' own information. These guys cleary THINK that MB is year one for sabermetrics and are trying to tear it down because of it. If someone doesn't like MB, whatever, but to state that it presents some kind of absolute predictive system is complete garbage and betrays just how little these guys understand what they're trying to counter. And the fans you described are not a "broad swath" of anything. Fans that casually drop something like BABIP are still very much in the minority of baseball fans, and this book is not addressing them. It's trying to take down what the authors see as much bigger and more sacred cows.
