I think it's more the culture of being "submissive". They will say smth like "thanks for your work" and move on like nothing happened.that asians having higher average IQs makes them more prone to following better decisions, but I barely hear about any drama from Nijisanji or Hololive JP members like every time I go on 4chan it is some retarded shit with Hololive, Vshojo, phase connect and Nijisanji EN members. Wonder if its because Japanese people are great at following rules than people streaming from western countries?
In the west though it's more normal to hate your boss and shit on them as loudly as you can.
