I think JLO wont speak because shes married to a big time guy.
Obviously she used him for the come up the same way Cassie tried to, but the difference is JLO was able to cash in for top quality in her community before ending up with the most high profile white guy(the same guy who swerved her when it was time to have his OWN white kids).. She has ended up on top.
Cassie didnt get the same ending. She married a personal trainer so they needed this big pay day with their two kids.
It could be that Jlo didn't experience what Cassie did. Not that Puff never did anything to her, but maybe relatively it was minor in comparison. Most abusers pick their victims well. More importantly, JLo wasn't exactly a nobody during her time with Puff compared to a up and coming artist like Cassie.
Does this potentially change the narrative that JLo didn't hold Puff down during the shooting shit? If the real reason she left is because of Puff's volatile behavior, that's alot different from when shit got real she choose her career.
