What is Bob Arum's Appeal?

This guy is obviously a successful businessman; I'm not here to argue that point, but I don't think he could be more of a gaping a$$hole if he tried. Gary Shaw says he wants to do Bradley-Valero in Mexico so that Valero doesn't have to worry about getting a visa to come into the US. Then Shaw gets the date, venue and an offer from Showtime, but says since he made the deal and Bradley is the champion at 140 that GSP is going to be the lead promoter. So, Arum goes berserk, calls Shaw "a fu(king idiot," calls Shaw's offer ridiculous and says Shaw ruined the fight by saying "incendiary" things like that GSP should be the lead promoter. That ruined any chance of Bradley-Valero happening. Now, Arum is saying that he "has no tolerance" for fighters who talk trash and that he won't do a fight with Mayweather. Arum has talked openly about doing a Pacquiao-Margarito fight, even though Margarito got caught cheating and basically ruined another of Arum top fighters', Miguel Cotto, career. He recently said to a reporter "fu(k Golden Boy" when asked if he thought his statements related to Golden Boy might make it harder to make Top Rank/Golden Boy fights like Pacquiao-Mayweather. I know a lot of you people on this board like to blame Mayweather for everything wrong with boxing. Arum is genuinely responsible for a lot of what is wrong with boxing and some of you, especially the Mayweather haters, just swear by this guy. I don't get it. I just listed two examples, but the guy $hits on everybody. Then he wonders why people at HBO don't like to deal with him. I don't understand what endears him to so many boxing fans and especially media people.
