@Insanityprism—
The thing is that if Disney were offered a hot property by someone
not already under contract, and responded unreasonably in terms of money or in terms of something else, that someone could and almost certainly would take it to another firm. So, the fact that the creator here is not being published by
anyone suggests that the creator is making unreasonable demands.
Now, it could be that the publishers in this case have formed a
cartel, jointly functioning like a
monopsony in an incontestable market. Cartels strongly tend to fail in free markets, but can buy sponsorship from the state in controlled economies; however, I wouldn't
presume the existence of a cartel in this case.
