A good example of a Pippa collab going sour after the fact is Coomalot. Also, no offense to Kirsche, but I kind of understand why an entertainment company owner may not want their talents openly and frequently collabing with her, seeing as she is leaning more and more into political shit. The talents do have their politisperg moments, but to be frank it is nowhere near as often or as serious as what Kirsche is doing.Gonna play devil's advocate here and say that while Pippa's no stranger to menhera moments of her own, she's surprisingly good at handling the internet drama that throws itself at her. She's dealt with collab partners going off the rails before and it's barely left a mark on her, which wouldn't be the case for other girls in the company who aren't as experienced with keeping their emotional reactions to current happenings at arm's length from their content. It's probably a practical consideration rather than favouritism.
Also remember we're hearing this third-hand so there may have been more nuance to the situation than it being a strict blacklist.
