They didn't. They've done nothing but heap effusive praise on her.
She's still traumatized about the way that she got roasted online by the general public after getting KO'd, and she's misdirecting her anger at the media.
The funny part is that the backlash was fueled by all of the over-the-top, hagiographic nonsense that was being written and said about her. It wasn't just Rogan calling her "a once ever athlete." There were a bunch of mainstream entertainment and sports outlets, who don't know a damn thing about her or MMA, laughably claiming that she was the most dominant athlete in history.
She was a fad who had her time and then fizzled out. Nothing that hasn't happened before.
