I can't see how that is going to stand up in court though, Zuffa purchased PRIDE because the parent company wanted out due to the whole Yakuza scandal, they purchased Afflicition and Strikeforce that were both hemorrhagging money and would have died anyway.
Now is probably the most competitive the MMA industry has been since PRIDE's demise, you've got Bellator who have the backing of a multibillion dollar company in Viacom and a large TV presence, WSOF are on TV and can pay Fitch $60,000 a fight, ONE FC is paying Ben Askren $250,000 a fight. Eddie Alvarez and Gilbert Melendez were both subjects of bidding wars that jacked up their salaries and got them guaranteed title shots.
I do believe that the guys at the bottom of the card making $6k/£6k need to be better paid though, you can't be a professional fighter when you're making less than $20k a year gross.
