Maybe I should leave this well enough alone, but I feel the urge to say something.

Knowing who you're talking about, though not knowing the details of this specific situation, I know of at least one case where this particular creator had actually given written permission for somebody to make and sell a specific fan product... and then took back that permission because of it queering the movie deal, and rather than explaining this and nicely asking the person who was making fan works to stop, they had their lawyers send threatening legal letters.

It's horribly arrogant for a fan to say, as you pointed out, that they have some right to make money, and I feel for any ceator who has to deal with that. But when one has been given permission to do so, it's a whole 'nother kettle of fish.

I suppose the person I'm thinking of could be lying, and didn't have permission after all, but then why would she lie when she did, actually, stop making her product the instant she got the cease and desist letter? A creator has a right to their own works, but that doesn't give them a right to go back on their word just because now it's queering their movie deal.

This particular creator is the only one I know of with an anti-fan club.
