I don't think there's a soloution mate...sadly. In the old days guys like Frank Ruiz used to go round to their schools (in the days when guys were buying a book and teaching from it to cash in on the world wide craze brought on by Bruce Lee) and bash them in front of their students and tell them to cease and desist. My old instructor Bob did that a few times as well. Probably can't get away with it nowadays.
As for not following their methods...no, I don't either in the martial arts because their studies have taught them the major market is 8 - 10 year old boys and I won't teach anyone under the age of eighteen.
You'll be happy to know that years ago I attended one of their seminars (by the guy who created the whole marketing in the martial arts business) and he was saying that the attitude of one in a hundred people can make it to black belt was wrong and that everyone should be able to be a black belt. (as that is what the "market" wanted)
I stood up and said "Isn't that a bit like saying everyone who joins the Army should be able to be in Special Forces?"
He replied "Well, why not?"
"Er...because they'd no longer be special!!"
The house came down and I walked out the door and went back to my ill lit, dungeon like dojo to teach my adults how to fight.
