I disagree.
Just as with physical products, you can't tell someone to whom you just sold a car what he can or cannot do with it, once you sell a copy of an IP, you don't get to say what they can or cannot do with it (as long as it's between the bounds of copyright law, which IMO should only concern copying for distribution, public performance, etc), no matter how much you might dislike it. If you don't want people making other stuff with your work because you might not like what they do, then don't sell it.
Otherwise, you're not "selling", you're just authorizing use for a particular limited purpose (or renting) and we should stop calling that kind of thing a sale.
Copyright somehow went from "I sell you this copy, which becomes yours, but you have to respect these few restrictions as stated in copyright laws" to "here's a copy of my stuff, you can do NOTHING with it except these few things which I state in the EULA, even although you paid for it and I said it was a sale."
Fuck that. You can't have your cake and eat it too.
