I imagine you refer to the M.U.G.E.N's license when saying "mugen's policies" which, according to the latest readme, prohibites you only of selling the M.U.G.E.N itself, not anything to use with it. So paid DLCs for M.U.G.E.N is not really prohibited.

Now, if you're refering to one's own common sense, it isn't THAT wrong, helped by the fact that donations will be directed to a fanmade Earthbound movie (which is actually worth it IMO).
