Regardless of the actual ratio of people that get it in contrast to those that don't get it, there has to be people that didn't get it and are directly benefited from his 'explanation'.

It's right up there with the people that post "clickable links" to a website. It might seem distasteful to some, but hell they are useful in a myriad of situations.
