Similar to people "teaching" martial arts/"self defense"/Close Quarters Combat: "And your attacker will hit you with his right hand, and you'll grab his pinky, and step on his toes to hurt him. Repeat until he says owie!".

It appears that most of the content about the deed is produced by people who never did the deed. That content theng goes through human centipedes.

However, I think that it is a spectrum. If all content about disciplines was only extremely technical and legitimate, it wouldn't spill over and reach people on the outside.
