This actually reminds me a lot of the way pyramid/MLM schemes worked back in the 90s (and probably still work now). I got briefly snared by one of these things as a kid, and the materials were certainly of high perceived quality (nicely bound, etc.), but it didn't take long to figure out that the whole thing was about selling the thing you were being sold. Similarly a massive proportion of Amway's revenue, and the revenue of successful Amway members comes from the sale of materials and seminars related to building your "business". The household products themselves are very much a sideshow.
All these deeply meta, self-referential product optimization products have a similar - slightly grubby - feel to them. Old ideas repackaged as new. I mean, I suppose fair enough if you can make a living out of it and you're not actually scamming anyone, but how many of these damn things does the world really need?
