@Dr. Ethan Charon has a curious legalistic view according to which it seems that nothing that hasn't been written in a contract is a promise. Thus, any kind of encouragement and help is, from this perspective, just a way of helping the other party to hack their own copy of the mod for their own enjoyment and does in no way mean anything in terms of promises unless a promise is made explicitly (which probably won't happen). People who have not encountered Charon previously are unlikely to understand that, as this is the only person I've encountered that act is this way.
