He got his name in the credits. The question was if he is owed anything else. The contract he created says he was not. I’m simply suggesting he might need a different contract.
But only after $$ was made.
If the comment above is correct, he was only added to the credits after he had to ask for it after the fact.
So the ONLY thing the license asked for is to be named and that was supposedly violated. So a multi million dollar company can just violate a generous license and then after a fact cling to this exact license while arguing to not pay a single cent more than the license asked for. Alright...
Only if he wants to force something different. Which it seems he does not.
I bet if you caught a homerun ball in a baseball game, you wouldn't give it to the kid next to you because "I don't owe the kid anything".
