I guess a good example in case of dominions is the in modding. Where people constantly reuse and alter existing graphics from the game. I suppose technically illwinter would have the right to restrict this (enforce their exclusive rights) and require all new graphics to be original, but chose not to as long as it benefits their game.

Still I don´t really see the point of your post. It is pretty clear from previous "discussions" that both Illwinter and shrapnel intend to enforce "their exclusive rights" where need be.
