>>93438609She got too popular and began to take the spotlight away from people they liked. This is not her fault and just the nature of becoming bigger. When you look at vtubers people know they tend to know Mouse now. They take it as a slight against themselves personally and their oshis personally despite mouse having never done anything to them or their oshis personally.
This was not how it was back in 2020 when they used to say nice things about her. Legitimately, with any kind of popularity comes haters. Like we've said many times, success breeds jealousy.
