Costa had 20% of his purse given to Marvin, and rightfully so, as he didn't make the weight agreed to in their contract and Marvin deserved an incentive to keep the fight from falling through. Similarly why didn't Anthony Smith get 20% of Jon Jones' purse when he failed a PED test before their bout? Jones was contractually expected to arrive clean and Smith had the option to refuse the fight, being at a disadvantage. Since he's a stud he agreed to fight but should have got 20% of Jones' purse.
