ASUSxHololive stream got cancelled Discussion (self.Hololive) submitted 6 hours ago * by seankao31
source:
"I just learned from the comment section that a regional branch of our company has a collab stream with hololive."
" 1.China branch isn't aware of this. Each branch is responsible for their own region.
2.However, everyone knows us as a whole brand, and being a Chinese company [1] we take it seriously. We hope to cancel the stream.
3.Hololive f*ck ur mom."

Nothing. Mainlanders are just that mad.
Hololive did have a strong fanbase by streaming on BilliBilli though, they might feel betrayed - by a picture of a Taiwan flag.
