Because she lives in a different reality to us. Every one of us has, at some point, faced consequences for doing something wrong. We've either embarrassed ourselves, hurt someone we care about, or had to face some kind of punishment for our actions. It's not nice, but no man is born perfect, and these consequences help humble us and point us in the right direction.
Froot, however, has gone through her entire online presence without ever having to accept consequences. Sure, she has critics, but there's always been something standing between her and actually accepting that she fucked up - whether it be /k/ simps excusing any misgivings they have with her because they want to fuck her, her position in VShojo meaning others in the vtubing industry don't want to criticise her out of fear of straining relations with their mutual acquaintances, or her SJW fans and friend circles who #BelieveWomen and feel the need to protect her from any perceived upset because of her "trauma".
She'll get away with this again. Nobody will cut ties with her because, in the current climate, ending a working relationship with someone after they talked about their ex-husband abusing them would be optics suicide, regardless of how reliable of a narrator she is. She won't even feel any shame, because as far as she's concerned, she did nothing wrong, and she's only getting backlash because of the nasty victim-blaming misogynists. She's told herself that lie so many times that she believes it, and her friends, co-workers, and mother reinforce it every time the subject comes up.
Every person is at least somewhat influenced by their upbringing and their environment, and Froot's entire life up to this point has been the perfect recipe to create an unlikeable, repugnant individual.
