Sadly, if the ufc were almost untouchable when owned by the mafioso fertittas, now that they are owned by Disney, they are government level untouchable. They posses too much money power and influence to be dethroned as mma's tyrannical and unethical monopoly now. Especially in the corrupt and backwards world this has transformed into today.
If someone had the money power and influence to take them over they would need to start with getting rid of Dana and reforming everything. Someone like Scott Coker has had good intentions and fighter relations to do it but not the right strategy. You need to fight fire with fire and aggressively attack the ufc , pointing out their malpractices in the media, taking them to court constantly over any breach of ethics, and educating the masses of cashew fans into accepting other brands not named ufc. A huge cultural shift is needed, I doubt an American org like Bellator would be able to pull it off. Only something like pride had the power to do it but they were subverted into selling out unfortunately.
