Organizations have to review their rules if they want to remain relevant. That percentage they charge needs to have a limit. And the limit needs to fair. There is no reason for a organization to get more than 100K from a fighter. Nowadays, and with so many organizations isn't the belt what sells. It should be 3% or a 100K limit. Whatever is smaller. Opinions???
The alphabet rackets aren't going to suddenly clean their act. They all make up the rules as they go along, and do whatever they believe is in their best self-interest first and foremost.
