Almost as bad as the videos of martial arts "masters" generating ki and knocking people over without touching them.
Students are the ones getting suckered out of $$$$.
I have taken a bunch of different arts over the years. Oyama Karate was good, BJJ was boring, TKD is for kids, the last art I trained was more a street fighting situation run by a Marine Lt. Col. who runs sniper platoons and does counter-terrorism. That was bad ass stuff.
