They ban them because they won’t censor factual information and won’t promote disinformation. See how Chinese censorship applies to mRNA vaccine conspiracy theories. A person that debunked them was banned from wechat. Do you see western governments doing this?
I haven't seen that happen in China either. How do you know it actually happened and wasn't some other rumour spread (since there's a plethora of disinformation both for and against the Chinese government)? To be clear, I'm not in favour of the Chinese regime but your particular point does still require a citation.

I’ll find the wechat story when I’m more awake. ADV china covered it though.
