Your youtube video comparing Jake Mace and your Grandmaster is interesting. I always like to find out where material is coming from, and how it was learned.
There are some problems, of course, with your argument.
#1 In a free market, we don't care if your Grandmaster Salvatero or whatever pulled the form out of his ass and called it a grandchild. What kind of "permission" does one need to pretend to be a tiger/crane? The form is hardly "strictly combat" and contains a lot of showy movements. Are you saying that your Grandmaster owns something that you learn--something that you put into your head? ?Your grandmaster owns your mind and its contents? If I memorize a poem by John Milton, does John Milton (who is dead 400 years) own the info in my head. If so, how? I do lots of one-legged squats, but I don't know the form. So must I ask permission of Grandmaster Salvatero if I do one-legged squats and pretend I'm a crane? Just silly.
This is why intellectual property is such a stupid idea. According to your rationale, I ought to be paying royalties (or homage) to the first half-man half-ape somewhere in the line of time who built a lean-to in some remote forest simply for the fact that I live under a roof today. Why not, according to your logic?
#2 Any competent martial artist could, in theory, learn a form from a book or a video. I don't consider it a good idea, simply for the fact that "forms" aren't that important when judged beside actual martial skills. But if I did know a tiger-crane form years ago, but forgot it when I....oh, I don't know...moved to Kentucky from Bandung, then would it be such a crime to fill in the blanks using a book or a video?
If this doesn't sound so outlandish, then the real question once again boils down to the problem of intellectual property and its legitimacy.
