Interesting conspiracy theory, but lets say they did. Why? To spend YEARS losing money pumping funds and resources into this bastard sport that was stigmatized and hemorrhaging money and was an absolute long shot to ever turn a profit? They were the right people at the right time and they had the vision to make the deals necessary and create a product that would go mainstream. You can't argue the facts: Zuffa took a company that nobody gave a shit about, that operated in a sport that nobody gave a shit about, and they turned it into a mainstream thing.
Fans will always say "they didn't do anything creative, the UFC/MMA would have been a great success without them", like any asshole could have done it. Despite the fact that the history of MMA is LITTERED with the corpses of MMA orgs that were not successful and went belly up. And a lot of these orgs popped up and went under after UFC did all the hard work in piquing the public's interest in MMA. There are a lot of great businessmen who entered the MMA industry and failed miserably. So when people say things like "oh anyone could have done what they did", I have to roll my eyes.
Hey, I get it. Down with "the maaaaaan", hate the big guy, down with authority, and all that other stuff. Like I said I don't agree with all of their choices. I wish the fighters got paid more. We can talk about hypotheticals and who could do what all day, but the fact is Zuffa DID it.
