Then the other code is developed to cause the arm to function. Code is a collection of ideas, same as a book. It’s not like rockstar’s code is going to allow a robot to stand because I’m pretty sure that sort of code isn’t developed in a game engine to begin with. Rockstar is coding for a platform that doesn’t run on the hardware that causes a biomechanical arm to function. I think a lot of people have the idea that FOSS should be every code ever, but when you look at the way that paid software does things, you realize it’s always a little more feature rich (not necessarily a smoother experience) because they can afford to pay a developer to develop the code. If GTA has some revolutionary ideas, then others can take the idea and find a way to skirt copyright just like they always have.
