I don't see any hate for her.
She was set up by the media and set herself up as the greatest gymnast of all time. She talked it up and so did everyone else.
When she quit I will bet that two things happened: Number 1, she cost herself millions of dollars. If I were a corporate sponsor there is no way I want her on my box of Wheaties. Number 2, she will never, ever get over the embarrassment of what this does to her career and reputation. I don't wish anything bad for her, but when you spend your whole life leading everyone to think this is your moment and then you say, "oh, never mind" people are going to look at you as either a quitter or a drama queen, just like Naomi Osaka.
