Not sure how I should understand your comment, but the link you posted is great. It clearly shows what a great place Shenzen is. If Silicon Valley is be the place for software startups, Shenzen is its equivalent in hardware. So much ingenuity combined with an extremely short manufacturing pipeline as described in the article. And as long as we are not talking about actual counterfeit products, I can't blame them for being inspired by known brands products. But unless we are talking acutally patented or copyrighted things, the concept of "IP" isn't as clear-cut as some company lawyers like to make it.
