I guess this shows not even the biggest JP Vtuber corpo has a say in who gets in and who doesntSakura Aoi (Chihiro from Niji JP) is also there, I guess you shouldn't read too much into it but it sure seems like they picked a side here. That's a pretty impressive pro roster too with some of the top JP teams being represented.
VSPO is also apparently unbothered by it, as well as some other big names from the JP Apex community - great news for Doki if she wants to keep participating in JP stuff (although I guess it won't always work out like this)
But MAYBE we will need more events to see how it really works
