Heh! It's funny when you break things down and stop listening to propaganda, you start seeing that there is an immense grey area, and that nobody is perfectly clean. Exceptin' ME, of course! I am always very wary of people claiming some sort of moral high ground, very often, they have skeletons in their own closets.
Let's say Sparks DID just copy Skymaster. I don't know if that's the case. Then this would STILL be just another "I-went-to-mainland-china-to-get-thirty-cent-an-hour-labor-from-this-communist-dicatorship-so-I-could-sell-what-they-made-for-me-to-westerners-at-a-large-profit-full-well-knowing-that-they-always-clone-everything-and-now-I-am-pretending-that-I-am am-all-surprised-that-they-did-what-they-always-do-thread."

What will people say when they find out that parts for their popular "Western" turbines were actually made by Jetjoe?
