The ridiculousness of this stuff is not the content, it's the linkbait hyperbole he uses to market it. He draws people in with shit like "The 4 Hour Workweek", even though his content doesn't say that's actually going to be the case - at least not until deep into the process. And it pervades everything he does - shady marketing tactics that cover up content that's actually pretty decent.
Are they shady tactics if they actually work and the content is decent as you say? The point of marketing is to get the eyeballs, if your content is garbage then that's a whole other issue. Maybe you can go into more detail about what's shady about his tactics?
