The UFC buys out major rivals and the closes them down like what happened too WCW. Also Dana White acts like abit of a Vince McMahon wannabe.
Your statement ignores other facts that happened as well. When WWE bought WCW it was because the WCW was for sale and about to just go belly up. There were some people trying to make a play for it but none of them could secure the funding.
Almost the exact same situation for PRIDE and StrikeForce. No one wanted to touch PRIDE because of the bad press/rep it had gotten, and no one could secure the funding for StrikeForce so the UFC bought both.
Your statement makes it sound like they were out actively trying to pursue these options when instead they just took advantage of opportunities that went their way. It's called how to successfully run a business.
