Misleading people is not ok.

It's so not ok that we have laws against misleading people. Not against this particular misleading (I don't think, although if Asimov had a formal estate they could probably sue).

I can't open "Tom Cruse's Fine Wine" because I'm not Tom Cruse. It's wrong morally but also illegal. We have laws against things like that and Tom Cruse would surely sue my ass, successfully. The proof of that is that there is no "Tom Cruse's **" businesses out there.

It might stop being illegal if the person dies because to sue you have to have standing. Unless there is formal trust like e.g. Tolkien's works and business affairs which probably have standing to sue "Tolkien's Fine Wine".

A child would also take offense on being mislead. Not this particular misleading because it only misleads people who know who Asimov is and like his books. Your hypothetical child doesn't.

But tell a child you'll buy him an ice cream if he finishes his chores and let's see how he reacts if you mislead him by not buying an ice cream.

You must have learnt this at some point.
