For me, it's just about advancing knowledge. Keeping MA secrets feels like keeping management skills secrets in the business world - it just doesn't make sense to me from a "big picture" point of view. To your point about arts that are waning - I'd prefer to see my primary art's (or even my personal curriculum's) effect on some unrelated schools, rather than see it vanish entirely.I absolutely agree. All this secret stuff is ridiculous in this modern age. In the past you might have wanted to keep things secret so the guy in the next village over wouldn't gain an advantage over you if you had to defend your village's wealth or honor. But nowadays it serves no real purpose. And it actually works against arts that are at a real risk of dying out, or of being transmitted with lots of bad information because the people that knew the important details wouldn't share that knowledge. This is just one more in a long list of reasons I have become rather disenchanted and fed up with "traditional" martial arts.....Wing Chun included. There is just too much BS that goes along with them.
