I imagine this could be a problem for any time a vendor has the manufacturing of their product done in China. When a vendor stops selling a product, and therefore stops ordering more from the manufacturer, there's probably no way to get the design back from the Chinese fabricator and they may either continue to make the product and sell it themselves, or have someone sell it for them in a lot of cases. As we know China is the source for a huge number of counterfeit items, and if they don't have to do any design work because they already have the plans, all the better. I have no idea if one can contract to get their design back from the Chinese vendor, but there probably is no way to be sure it hasn't been duplicated even if there is an agreement. We don't have a lot of reach into Chinese manufacturing, I don't think.
