Long article, lots of info.

But this about wraps it up -

What were the plaintiffs of the lawsuit alleging was the percent revenue that went to fighters? And what was their methodology to determine that? The reason I ask is that I think it was similar, and I'm just curious if they arrived at the estimates independently.

The main difference is those sports had labour support and unions long before modern capitalism ate itself. Zuffa's just doing what any company founded in 2003 would do/been encouraged to do.
