You shouldn't be pissed off at China for ignoring the IP of the developed nations and using it to catch up. That's what countries at their stage of development do. The US did that early in it's history, especially with fabrics. So it's a bit hypocritical for the US to have used those techniques to advance their economy and then try to deny China the same thing. Either that or admit that it was wrong for doing those things in the past.
