But you’re not profiting off of it. The corporation is. They have no incentive to give you credit, every incentive to claim that they made it which they would of course be allowed to do. They could even start making their own derivative pieces or continuations. The artist has gained nothing from this hypothetical.
Eliminating copyright doesn’t mean they’d be allowed to lie about who wrote what they were publishing. Anything an artist creates blowing up and gaining wide appreciation is very good for that artist’s future prospects. An artist who is spreading their work for free anyway is much better off in the scenario where there’s no copyright and everyone understands the need to tip / patronize their favorite artists.

That is literally what Copyright is. Removing it means exactly that.
