Because this was the key part of the quote from Geezer that Hazardi was responding to was...
So I was pointing out this was indeed the truth as it was used by YM's Association first and then noted the one person who, to my knowledge, did actually trademark a different spelling.
I'll leave it at this because as was just pointed out, nothing good can apparently come of this.
No one said WSL trademarked the VT spelling, but that's the spelling he used because YM did.
Those who have changed the system under WSL have used different spellings or renamed their systems.
"Gary Lam Wing Chun" is one example.
"Wan Kam Leung Practical Wing Chun" is another.
