The way I see it, no matter who their management is, they work for each client individually and do their best to get each client work - even if it's competing with each other.
If two actors have the same agent in Hollywood - and I imagine a lot of them do - the agent/management would send all suitable clients up for a role no matter whether they are competing with each other, because they are working for each of those individual clients interests.
Same with these low-rent personalities. If the girlfriend got offered money to go in, I imagine - as it's money for her - the advice would be to go in. They wouldn't say no, don't go in, it will adversely affect another client, because when dealing with one client they are the priority.
I also don't think that, with regard to Bear, showing him up to be a cheat is news to anybody watching the show and reading social media is news to anybody. Those who support him admire his behaviour and will continue to vote for him even if he murders somebody on the show, so I really don't think it matters what kind of light this show him in. His supporters like that he's this way.
Just my opinions, obviously
