Eh, what if that is the reason a developer won’t fix an issue?
You can make rules about what people can post on your forum, or who has the license to modify your game (actually you forfeit this second part with the license you chose). But you can’t change other people’s reasons for not doing something.
If you tell developers they can’t respond to a bug report by saying, “yeah, that’s a problem but I don’t have time to fix it right now”, then said developers aren’t going to post a response to those bug reports at all.
I struggle to understand your rationale here since all mods have to be open sourced anyways.
