Its the work of the creator and as such he can slap whichever license on he wants.
BUT you can enforce a licence if the mod want to be distributed by a given, preferred, distribution chanel. You could say that to appear on Josh's best mods website or on any other online platform, a given licence is required (for example Creative Common with attribution, share alike, no "no derivatives") the option of allowing comerical usage being open (and irrelevant).
MOREOVER, Josh could force a mod to have this licence in order to be interpreted and used in the game. For example by checking if there is a standard link to the CC licence
at the top or so.
Not saying these are good ideas, but saying it could be managed, if it is desired.
