All of you are looking WAY too in depth at what he's tried to create for a GB. I think, from my own perspective just by reading his original posting, his intention was perfectly simple. Between Dragon, Tamiya and Trumpeter you could pretty much build anything under the sun and more often than not 98% of GB entries are made by these three and his suggestion was to not include any of those three in whatever each individual chose to build that joined the GB. Given it changed a few times and, as far as I can tell, is excluding everything from the Asia's and is including stuff from Europe/Russia, (I'm being worldly vague.)
Personally if I were running the GB I would limit entries to manufacturers based in, or originated in, the United States/Canada, not where the plastic was melted into sprue form and plastic wrapped into boxes.
Everyone looked at it and read it from an entirely WAY too political view. Given some statements were made in an not too entirely serious politically referred manner I don't think anyone was being overly austere. Take it for what it is, your picture isn't going to be posted in every hobby shop with orders to never allow you to buy from the "big 3" again. They are plastic scale models, this isn't oil trading.
(P.S. Yay Honda, Toyota, Nissan, Mitsubishi, Subaru and sometimes Mazda! AK's are horrible even given their drug through the mud reliability and short range stopping power, YAY to the FN-FAL! (Just to chime in on other subjects and hopefully not create an uproar of epic scale modeling proportions 
))
