If the truth be told, the Kukkiwon dosnt care a less what you teach as long as you send in $$$ for certificates. Not anything against those who tested in Las Vegas (thought about it myself) but take a look at it from this view.
They tested people that the didnt know, didnt do background checks on, and didnt know the following:
How many times the actually worked out... every day, once a week, once a month, never....
If they were school principles, congressmen, child molesters, rapists, ect.
If they were legitimate martial artists or someone who just wanted a piece of paper to make themselves feel good.
You also wont see anyone from the Kukkiwon doing the following:
Visit your school to make sure you are teaching Kukkiwon TKD or "Joes kicking stuff".
Revoke or otherwise take action against one of its "certified" instructors. They have no dispinairy policies in place and no matter what "rumors" you hear about revoking certificates it just dosnt happen.
WTF couldn't care less if you know palgue or Taeguk forms.
Not true.. The WTF world poomsae championship only use Taegeuk and Black belt forms,not Palgwae
