He seemed pretty upset overall with the UFC tho.
Oh I saw that interview, I see what you're saying
It's a very layered dynamic between Jones and the UFC
I don't think he's upset with the UFC in black and white terms. In the interview he said himself that he is not bothered by the UFC's promotional and marketing techniques that paint Jones as the "bad guy". He did say he looks at the UFC differently, since UFC 151. He felt the UFC "turned on him" when the card got cancelled and they "weren't the family he thought they were"
The UFC did drag his name through the mud and muddy up his image
In the present though, he isn't as naive as he was before, he understands how the business works now. Originally Jones was upset about how the promotion for this fight portrayed him, but he sat back and thought about it and admitted it made for good T.V.
Besides that, he got a new contract from the UFC so I don't think he's really that upset with his employer he just understands that they aren't his friend or family
Just to add to this, GSP and other top stars get a cut of the PPV as well
GSP and probably other top fighters make well over 400K per fight, how much exactly is up for debate
