IANAL so I don't know. But imagine the time investment required to do so...
Now, personally I would probably respect the clearly stated intent of the author, because I like to think myself basically decent. But I also try to advocate for people not undermining themselves by selecting licenses that actively permit people to do the thing they don't want them to do. If you want people to contribute back to your ecosystem in exchange for licensing your code, don't use a permissive license, use a copy-left. If you don't want someone building a business off your code, use a non-commercial license. If you want to put any meaningful restrictions at all on your codebase don't give people a carte blanche to sublicense it.
