Actually, I think lack of respect for patents and copyright laws is probably one of the big drivers in the Chinese economic boom. Because there's no artificial limitations on what you can build and sell, all manner of artefacts are effectively 'open source'.
This poster was clearly not suggesting that the Chinese find a cool product, steal it, and then update and innovate and use the community to develop new stuff. Instead, "open source" is being misused in place of "free". The poster's comment about Windows is that, much like open source linux, you can go online and easily find and download the latest version for free. In context, his meaning is pretty clear.
Our business in life is not to succeed but to continue to fail in high spirits. -- Robert Louis Stevenson
