>>14237137She still can mention her.
>>14237197No, it makes sense from their own perspective too. Think about this, she can say "Friend C" exactly because we all know who she's talking about. She doesn't break any sort of rules and she doesn't name any specific names. It's the perfect middle ground.
Kanata doesn't exist for kson either so it's only fair. There IS a chance she is forbidden from mentioning Hololive in any way but that's some black company stuff if Cover still controls her on such a petty level when her online persona isn't affiliated with them anymore. But I think there's a higher chance it's just her choice. I personally don't see anything wrong with it.
