I was considering posting about this very same issue a month or so ago when I first discovered 'made in China' BD cams and shortly thereafter found a bunch of other Chinese-made BD hardware. I've worked in the computer hardware industry for years now, and have had the chance to visit plenty of Chinese manufacturing operations (including companies in Zhuhai, where I believe BD's products are manufactured). It's a mixed bag for me, I've come to terms with nearly all tech products being made in China, from the components to the final assembly. However, it still struck a chord seeing the 'made in China' label on BD gear. I've spent many dollars on BD gear over the years (I've bought lots of stuff directly from Jeff, he's a great guy), some of it on stuff I knew was Chinese-made (tents). BD gear has been some of the most durable, well-designed gear I've owned. I don't doubt that BD has "moved" their quality to China as well, stuff made in China is as good quality as the company making it wants it to be. If the goal is cheap, they'll do cheap; if the goal is good, they'll do good.
However, I am still uncomfortable buying Chinese-made climbing gear. I'm sure I'll come around eventually, either by choice or because there are no other options. As irrational as I know this is, my money will go elsewhere for the time being. (I also will not buy Chinese-made skis.)
As a side-bar to this thread, when a company opens a manufacturing operation in China it is usually the first step in series that culminates with the vast majority of work moving off-shore. As someone else pointed out, the supply chain is often next in line to move, and then most new investments go to China because the costs are lower. The transfer process often happens under the auspices of "expanding where our growth is," and then ends up as the same old "low cost manufacturing" for all markets.
