Its possible that being friends with the core group is actually a negative rather than a positive. You don't want to company to be known just as the club of friends of Nyanners and Ironmouse, but rather be an agency that promotes and supports talents.
There is also another more insidious and corporate reason, which is that you don't want the employees to be in bed together with each other. That gives them all the power. Thats what happened during the Nux drama, management wanted to ignore it, but Nyan and Vei got spooked, which then led to Mouse calling out Nux publicly, which led to all the girls banding together and acting in unison.
