Not sure if I'm understanding you correctly but my criticism of the book is that, while it has interesting ideas, a large chunk of it reads as: "We do this thing at Basecamp. Most other companies don't do that. And because of that, Basecamp is an awesome place to work and other places suck.". Instead of, you know, giving a slightly more balanced account of certain things or acknowledging that even your own company has flaws (every company does).
