People need to start somewhere and they are more likely to succeed in the short and medium terms if their program is a simple, straight forward black-and-white arrangement. Most people won't make it through to the point at which they max out their gains possible through this program and most that do will have developed by such time the sense needed to find the further information necessary to continue progressing. Moreover they will already be sufficiently motivated to do so at a high rate. If the complete beginers were exposed to all the incredible variety of information with all its esoteric aspects and led to believe that no particular program was "best", they would soon get lost in the details and give up just as you or I would if thrown into a graduate level math class without proper preperation.
As for the radio show I'm curious to see where it goes. I assume it will continue to be marketed at this same crowd, but without knowing his current financial ties, it's difficult to predict with much certainty. The guy has enough knowledge on a variety of topics that he could make something interesting if he lacked the financial incentives to do the contrary.
