>>12144874Here's the objective take, disregarding any consolewars tribalism:
Cover has their own proprietary in-house live2d app. That maybe would be advantageous, if it were a really advanced app (and maybe it was, a few years ago when it was first developed), but by now it is woefully lagging behind compared to what's available out there with third-party solutions.
You see this when other vtubers, who are not locked down with Cover's outdated tech, can for example freely and quickly add moving props and pieces to their model, whereas the Holos have to make do with static pngs, and have to wait around until the bi-annual official model update is doled out by the company.
This also touches on some "institutional" issues, especially comparing Hololive to something with less restrictive corpo autism like Vshojo. If a Vshojo girl wants a new model, new rigger, new props, whatever, she can just go and commission it herself and receive it in a short time. She doesn't have to ask management, she isn't locked in to some proprietary app ecosystem.
Cover talents, on the other hand, are and because the company is the one holding the keys to the app, they can tightly control everything about it. What artist you get assigned, what rigger, what props you get, and when. There's very little you can change yourself. Also there's very little you can do with you own initiative, for example the richer/popular Holos could, if they were truly "free", simply buy themselves dozens of different model updates all they want, whereas the poor/unpopular ones would be left in the dust. Cover, for "political" reasons (talent unity, cohesion, preventing them resenting each other, etc.), is against this and rather doles out model updates slowly, but more on a per-generation basis.
