It's not really the UFC's fault that multiple MMA promotions have also been attempted, and failed as businesses. No non-UFC promotion (Bellator, ONE, Rizin, KSW, Cage Warriors, LFA, etc.) has turned even a dime in profits in the last decade. And Bellator has signed multiple famous UFC fighters (former champs like Benson Henderson), including some (Phil Davis, Ryan Bader) at the height of their career. I don't think their ratings even budge a bit when these ex-UFC fighters are on.

I don't think the UFC should have been allowed to buy Strikeforce, and I think many of their restrictive contract provision should be struck down in court. But it's not the government's fault that none of the UFC's competitors are unable to turn a profit, and I don't really see a role for government there overall. If some business models don't work in practice, they don't work
