You can disagree as much as you like, but the simple truth is that the majority of vtuber viewers are here to see cute anime girls, whether you like it or not. With that in mind, then clearly collabing with male vtubers is going to be a debuff, which we have seen time and time again. Now if a talent wants to collab with a male they definitely shouldn't get harrassed as that is too far, but they have to understand that a good portion of their viewers aren't going to like it, ESPECIALLY within hololive where CGDCT is essentially the norm. So then they have to make the decision if the drop in popularity is worth "owning the haters/talent freedom", and that's a personal decision that I feel SHOULD be respected, but at the end of the day they will have to deal with the consequences one way or another. You are selling a service, and if the service isn't what people wanted then they will stop watching/buying. Welcome to simple economics and vtubing I guess.
