I'm concerned that the context of the OP implies that they're making this declaration after they've already sold products. It specifically mentions already having products in classified networks. This is the sort of thing that they should have made clear before that happened. It's admirable (no pun intended) to have moral compunctions about how the military uses their products but unless it was already part of their agreement (which i very much doubt) they are not entitled them to countermand the military's chain of command by designing a product to not function in certain arbitrarily-designated circumstances.
