>>103011349Roberu doesn't like EN in general, even the viewers since they annoyed him and ditched him.
Izuru had several bad experiences with western viewers to the point he became annoyed with them and refuses to speak English on stream much at all despite there being various signs he knows it very well.
Oga has shown slight annoyance with them but he's usually very professional, so that's already kind of extreme for him. The MC thing probably annoyed him really badly.
Astel at one point rather disappointedly noted that they didn't do much with JP and seemed to just fuck off, I think this was around the time he talked about how nobody in holostars tries to succeed.
Can't remember anything to do with the others.
