Your Disillusioned, Bro. Yeah, things have become semantically "This is a Kong Vault" or " This is freeRunning not Parkour" This happens with any Art form and even life.
The child is fearless, blank, receptive and capable of acting without thought. Then we grow up a little and start learning things, we put names on actions like strategies of Brush strokes in our lives. Then we reach the "Master" level. This is when life becomes a blossom, we can act without thought, feel without doubt and be without care. This is the fundamental of all Gung-Fu.
I understand your issues with the "Words" and Dogmas. BUT, the fact that you use your Psudo-inlightenment to insult and judge instead of teach and progress just proves that you are Simply entering the second state of life. The anger you feel is Growing Pains, mate. Dismiss your anger of the system and instead do what you can to improve it.
We are all a part of Parkour. We are the cells in the body of the art form. If we don't grow stronger, It can't grow stronger.
