They are the ones that had wanted cotto vs Canelo from what maricio Sulaman states when he says that they have been working for 2 years to get that fight, now that's what they are getting the fight that they wanted.
Yes, WBC worked hard on making this fight, but Cotto behaved as an ungrateful pig, so WBC had to take the belt. Cotto's purse announced today is $15 mil (with Canelo $5 mil), so 3% sanctioning fee publicly posted on the WBC site would be actually $450,000. It means that they did cut it to $300,000 for Cotto, but he still refused to pay. I doubt that Cotto's split would be 75% if he didn't have the WBC belt, so he deceived everybody -- Canelo, WBC and Golovkin. He is the scumbag in this situation.
