Korean Karate?

[Balrog]

Now originally I understand that this was a commercial decision since 'Karate' was much better known as opposed to TKD, TSD & HKD. But nowadays, that really doesn't or shouldn't apply should it? This isn't the early 60's where no one has heard of TKD, TSD & HKD. Should it still be used?

Yes. "Karate" has become much like "Band-Aide" or "Coke". People do not know the difference; if you're in your PJs and yelling hi-yah, you're doing karate.
