>>28852629There's many reason but sunk cost fallacy is I think a big one.
Because nobody has the time to watch/be a fan of everything, they need some reason to excuse themselves above all else as to why they're not choosing another option of a similar thing. In this case, because NijiEN is clearly full of people who think they're now too cool for Hololive yet they need to constantly tell themselves, condition themselves, as to why they "left" Holo and can't just watch both if they want. The cost here being simply time at minimum makes it a pretty fucking petty thing to get pent up over.
Another reason would be ideological - some people see Niji as like the anti-Hololive and try to embody it as such including I think many of the talents themselves. However, this isn't fucking true at all in the legit sense because NijiJP operates on a wide spectrum and many of their biggest talents like Lulu are actually not that fucking different at all from how most Hololives run, and to take their most sleazy examples and say the whole company is like that is like taking Coco and saying all of Hololive is like that when it's just not true. Of course, this fact is utterly fucking lost on most Niji fans because they objectively knew almost nothing about it at all until NijiEN existed. But oh well.
