Now you’re the one making ill-fitting analogies. Aaron Paul doesn’t have to do any addition labour each time someone watches Breaking Bad. He’s not required to be in the barn, it’s just got an image of him painted on one wall.
To over-extend the analogy further; if I build a barn and the farmer agrees to pay me $X for each cow living it, what should happen if he starts storing wheat in it instead? I signed a bad contract, but it’s still the terms I agreed to. I’m not automatically entitled to go back and change them.
What about a sign that simply says “Everyone is welcome here”, would that be acceptable to you?
