I dont think its that at all as it isnt hard to read through studies or just ask him to gain knowledge about a product.I don't think a lot of people have the required knowledge to represent his products
My take on it is that he doesnt have a bunch of reps pimping his products because thats not how he operates. Most companies operate by a different set of standards. Plug our companies product into every single thread possible or they have a minimum post count that must be met on those products.
Im not saying every company is like this but a lot are.
