Yeah Jones would get sued and probably kicked out or worse if he hit Dana White.
Jones can go anywhere else but people wont follow him. Only his hardcore fans will go where he goes. Other hardcore fans will just download his fights and regular fans wont even know he left. And his pay would be cut more then half... Jones probably makes a million or more if he fights... with a different company the best he can probably hope is around 200k.
And if Jones hits Dana White for no reason then it isnt likely Jones would get support from other fighters either.
