Hard to tell what “to their satisfaction” means though. It’s not beyond the realm of possibility that Bungee said “either you take just the end title credit or we yank your art and you get nothing”
Considering how much shit Bungie ate over this (and rightfully so), I doubt they would’ve gone this route. All it would take is one Twitter post from the artist saying Bungie tried to stiff them again and the whole controversy gets reignited all over.
