Vtubing industry would be better off if Nijisanji never took off. They popularized Live2D low effort streams and endless new generations to overwhelm the oldschool-style vtubers until they couldnt keep up and fell into irrelevancy. Nijisanji indirectly contributed to downfall of Ai, killed Akari, and hurt Siro. Think of random vtuber you liked from before 2018-2019, if they stopped growing or retired altogether, its Nijisanji's fault. The creative landscape full of new gags, concepts, and gimmicks that characterized early vtubing during oyabun's reign was replaced with samey boring stream format. Everyone else like Hololive are forced to adapt at the end. You can see this clearly on the fact that Sora, Miko, and Robocco were 3D since their early days.
