The worst thing a vtuber can do for their popularity is to state their opinions. Not because they have bad opinions or they are not allowed for any other reason, but because of how fickle the audience is.
Most viewers don't want to hear about something that them and the vtuber might disagree about, and once they realize that she is, in fact, not just like them fr fr, it puts them at an impasse, and very rarely they will decide they were in the wrong, instead they'll blame the vtuber for ruining their fun. Viewers are not looking for a unique perspective, they're looking for self-validation through a more suucessful person and when that person is not smiling and nodding along their whims, they'll switch off or worse, get angry at the vtuber for shattering their self-esteem in such a way.
Look at who the most popular talents are in HoloEN: Gura, Fauna, Bijou, FWMC, Ina. All of them are successful because they let their viewers run the narratives and don't say anything that would cause major dissatisfaction. On the other side of the spectrum, you have Mori, Kiara, Shiori, Nerissa, Bae, Kronii: all of them are strongly opinionated talents who will clash with the masses if they find themselves hurt by them.
