WTF does UFC being bigger than M1 have to do with putting M1 logo on part of the mat during shows that featured Fedor that's all it was free marketing for M1 it's not like M1 was gonna own a part of the UFC, all of what you said is just what you think.
It has everything to do with it. They're co-promoting the show, but M-1 doesn't bring anything to the table promotionally. They're literally just getting credit and free exposure for letting one of their fighters fight, which is essentially just them being a glorified manager, but unlike most managers they are asking for more than money. M-1 is getting a lot more from the deal than the UFC is, if you're UFC, which doesn't need Fedor to exist (clearly by how they are worth billions now), then it isn't a good deal.
Having a show that says "M-1 Presents: UFC 87: Fedor vs Lesnar" hurts the UFC's brand. Why on earth would you accept that if you're the UFC? Does Coca Cola co-promote with RC Cola? Did WWE, under Vince McMahon co-promote with anyone after they went public? No, because the WWE is the premier brand, it only helps other companies by co-promoting while not getting anything itself.
It'd be a ridiculous proposition for a company as big as the UFC to do that with a tiny no named company. Heck, we can even use you as an example. Why don't you make a promotion and then go call M-1, ACA, KSW, Rizin, ONE or any one else for a co-promotion, why do they say no? Now apply that to the UFC and M-1.
If Fedor was Connor McGregor or Brock Lesnar the UFC might consider it, but Fedor himself isn't so valuable that the UFC would allow another company to say they're promoting their product, when they are not.
The people who know what the UFC know what they are doing, and no one who is well educated in business would have accepted M-1's demands. Financial compensation was what would get the deal done, of course the UFC isn't going to let M-1 own one of their shows, do you honestly realize how insane that is what you're saying? Do
you think you should own one of their shows? Because you're closer to what M-1 is than what M-1 was to the UFC.
As for the "it takes two" thing, that is fine for M-1 not to let Fedor go. Would M-1 have benefited from Fedor fighting under the UFC? If they were able to get Fedor back afterward then probably yes. If not, then M-1 was smart to keep Fedor to themselves and offer demands they know the UFC will not meet. But this has nothing to do with Fedor's wishes or being scammed by low pay, it is entirely between M-1 and UFC.
It isn't anyone's "fault" why Fedor did not fight in the UFC. Fedor was not a free agent. M-1 did not want him to fight for the UFC. That's it.
