Because she doesn't give a fuck about it anymore? It's not like she needs any "gain" now. She probably can retire comfortably now unless she is extremely retarded with money.
She was a professional idol in Hololive. She isn't one any longer. At most, she is only doing the "idol" thing as a hobby now and at worst, she doesn't care about being an idol and only want to sing and dance now and then.
Since she doesn't need to care, she can interact with anyone in whatever way she wants to
