We all have such different voices and we all add something that the other person can’t. Like [Camila] can’t do Normani and Ally’s whistle notes, Dinah has such an amazing vibrato, Lauren’s really good at putting in like a kind of soulful tone. Everybody knows that they have something so important to contribute.
I don't think Camila wanted to come out. She wants a solo pop career. Lauren was so heartbroken in 2015 and spotted having several breakdowns by fans. One with Camila coming out of a bathroom. 2015 is also when Camila's solo career started being. March/April/May was when something changed with Camren and all the girls. Remember how protective Normani, Dinah and Ally were of Lauren during all those interviews that summer. I think Roger or the label forced Camila to distance herself.
