Point is: what qualifies you to decide how those old assets should be used? Because you love the game more than the original publisher allegedly does?
So by that logic, why does anyone care at all what the original MAME contributors think of their code being switched into an open-source license? Why are their requests any more or less important than the publishers?
The point of this hand-grenade was merely to point this out, unpopular an opinion as it is. This whole thinking of "I'm a fan therefore I decide" took us over the cliff a long time ago and there's no going back.
