I only got as far as reading the introduction but that was enough for me, I found the authors style to be not to my tastes and the book just seems to push the same old tedious rhetoric. Within the first three paragraphs the Open Source = GPL assumption had been made, which wasn't a good sign. That said the premise that software often has costs other than initial outlay seems perfectly reasonable (if somewhat obvious).
Strangely a quick google seems to reveal a large number of forums and message boards being spammed with low content posts regarding this publication. *Shrug*
