A big part of how well the niji stuff played out for her was random third party people and companies who'd worked with her on merch or conventions and stuff coming out of the woodwork to say they didn't need to know the ins and outs of what was going on in niji first hand, they thought highly enough of her that they immediately trusted she wasn't lying or overreacting.
Being of really good standing in the industry, at least the western part, does a lot of work. Nobody is less than effusively positive when they so much as reference her. That perception permeates into the general vtuber audience and creates a genuine impression that she's a nice person and its nice that she's successful.
