Years ago when I worked in audio sales, we all knew which items paid the huge commissions.
I could make more selling a set of cables or some fancy "accessory", than the actual electronics, or speakers.
The more silly or useless an item, the higher the percentages we got on them.
So there has to be an incentive to push stuff like this, just as there was years ago. I tended to not lie to people, but if they truly wanted that stuff, I would not talk them out of it either.
So I feel like guys like Danny and Ron, see potential sales and customers and dollar signs before anything else. Greed, and lack of being honest.
