Query: An exercise in cynical plagarism

Some time ago I read the excellent "Let's Get Real Or Let's Not Play" by Mahan Khalsa. Seeing him listed as one of the authors of "BusinessThink" I bought it. Only then did I discover that Khalsa appears to have had very little to do with "BusinessThink" (in a long list of acknowledgements he doesn't even feature) and, more seriously, that "BusinessThink" is essentially just a rewrite of "Let's get Real" - indeed whole swathes of "BusinessThink" consists of word for word plagarism of "Let's Get Real". Had there been some acknowledgement of this fact by the authors or Franklin Covey this practice might, just, have been okay. But there is no hint in the introduction, or elsewhere, that "BusinessThink" is just a slightly reworked "Let's Get Real". Shame on the authors, on FranklinCovey, and on the publishers for this exercise in cynicism.
