As best I can tell a producer named Cam produced 3 joints on Acid Rap, and is credited as "Cam for J.U.S.T.I.C.E. League". So he was likely working under/for them on a production deal. Chance is saying he paid the person who really produced it
For what its worth, Jake One has also said he wasn't paid for his contribution on Acid Rap, but also sounds like he wasn't expecting to be.
