Nobody talked shit about her, because nobody talked about her, period. People are talking about her now, because the termination is big news, and there's an actual reason to talk about her. Normal people usually don't go out of their way to watch or talk about people they don't like, they just spend time engaging with people they actually like.
Yeah, I know how ironic it is to say this on a KF offshoot, but sane people watch lolcows because they enjoy laughing at their dumb antics and consider that content, not because they intensely hate the person.
What happened with Rushia is completely different, she was always menhera, but she never really drank the entire bottle of dumb bitch juice until the incident that ended her career, and the way she handled it a big part of the reason people started to hate her.
