Artist Jingna Zhang built Cara, a platform explicitly intended to protect artists from having their art stolen by AI...and yet these people just won't leave them well enough alone.
Where you lose me is the idea that one person coming up with a recipe means they can set any kind of limits in how others consume it. Even if they want to blend it into a smoothie or stick it in a fire until it's nothing but char. They can be an asshole depending on how they do it, but I don't think morality enters the equation at all.
