No way! Who would have dossiers of all their favorite talents ready to nuke them from orbit if they turned on the Pippa? That's crazy.
I think if Fishman does what he says with PC's money, they would be okay financially, but would be completely stunted and probably take a huge rep loss that can't be recovered. That is, not over spending and always having a budget for the months ahead and planning ahead. It would be a huge loss for them and a huge upset, pretty much regardless of the reasons why they broke off with Pippa. I really don't think they ever would ditch Pippa unless is was something so bad that it forced their hand, like legal issues. Even if she couldn't stream for an extended or indefinite time, I don't think they would graduate her. The idea of getting rid of her for some other opportunity just doesn't seem realistic at all. How is somebody going to be offering them enough money to make giving up their biggest star make any sense?
