The theory is that you can get away with a bit more in China if you have a big western audience. She had a fairly big one and that was protecting her, but the audience is fickle (made more fickle by Musk ruining Twitter) and once her audience declined, she lost that protection.
I guess the real lesson is that if you're Chinese and develop a Western audience, us that to escape China. Don't stay behind in China because your big audience is painting a target on your back, and eventually the Chinese authorities are going to ruin your life.
As an aside, did anybody else find her vibe really offputting? I liked her content, but her enormous fake boobs and skimpy outfits were a distraction from otherwise interesting content. If I found a video of hers interesting, it made me not want to share that with anybody because they'd think I was watching it because of her body. I'm all for women's empowerment, if someone wants to look and feel sexy that's great. But, with her stuff, it was so extreme that it felt like exploitation. Maybe she was exploiting herself, but it still felt icky.
