This certainly sounds the right way to do this.

But I really wonder about the stuff at bungie being "just" incompetence, because their defence is "weren't aware of this, just used assets left by a former Bungie employee that's not here anymore"... And yet the art director had been following the plagiarized artist on twitter this whole time.

And they have an history of "just taking" when they think they can get away with it, as they've done with fanart. So, shitty studio culture sounds a definite possibility at that point.
