Nijisanji's innovation was developing a phone app for people to stream anywhere. This uses their own custom in-house software. The rigging is not as good as the normal software everyone else uses. Hololive basically just copied everything Nijisanji did. So they also developed their own app with their own in-house software. And so their rigging is miraculously, somehow even worse than Nijisanji's.
As a result, the two big corporations have some of the worst rigging in the business. It means if anyone wants to join the big corporations, they often have to trade their model for an inferior one.
