It's one thing to sell products to a country. It's another to sell them products that can be used for military purposes. It's entirely another to sell them entire businesses to their government, that can be used for military purposes, and to compete against other American businesses.
So? It's just capitalism in action. Unless the government has declared PCs a restricted munition, I can't see what business it is of their's.
And there's so many items that *can* have a military purpose that I have a hard time seeing where the dividing line would be.
