This will be the chain of events once the UFC has decided they've had enough of his antics:
1) They strip him of the belt and the ppv cuts.
2) If he's still not willing to fight the new champion, they'll stick him in the prelims and let him fight out his contract against promising prospects while the new champ builds a name for himself (this will happen quickly once DC and Alex fight each other).
3) Dana turns up the volume. Calls him a coward and a duckard and reminds everyone about how outspoken he was about his dirty eyepoking techniques which btw, was the only reason he ever won a single fight. He suspects letting Jon know that he was serious about coming down hard on the cheating is one of the many many reasons he chose to tap out and leave with his tail between his legs. And seriously, who didn't see Gustafsson kick the shit out of him? Dana vividly remembers Jon laying on the stretcher with blood coming out of his eyes, ears, mouth and nose; kicking and screaming and praying to God; while Gustafsson was doing sprints up and down the corridor looking for Jon so he could finish the job.
4) Jon leaves for Bellator to fight a now 50 years old Tito for scraps. One or two journos dares to question Dana's decision but are quickly shut down: "Jon Jones?! You mean the dirty dirty scumbag guy who wouldn't defend his belt? Who is he fighting? Tito fucking Ortiz is who he is fighting!! When we cut Tito he'd won one fucking time in his last eight fucking fights!!"
5) Jon's fans tries to make him a martyr but the sharks are all over them, trolling them so hard a Jones fangirl is dying by the ban hammer every minute or so. Those who remain on Sherdog are demoted from the heavies to Worldwide MMA Discussion, where they rage 24/7 out of sight out of mind.
6) Jon loses his first fight.
7) End of career.
