We all know there is tons of models of cars and planes in various market places and they accept them. It seems doubtful that it would even be worth while for the origanal manufacturer to go around stepping on little people. Mp3's went unchecked for a long time until the day finally came. Not to say you can't still download pirate music anymore. They handled it by making an example out of a few folks(even some little kids got hassled). This gets the message out and keeps the honest honest. The true pirate is going to keep on doing it. A law can be made, but that doesn't mean it's easy to enforce. I'm sure Lockheed and Boeing could reach out and touch you if they want too. Will they want too? Who knows?
