Anonymous Twitter users are exposing the extreme nationalism and pro-Russian sentiment circulating online in China – and Beijing is not happy about it.
Of all the ways you could possibly interpret it, you deliberately chose the most most ridiculous interpretation.
A more reasonable interpretation is to note that internet atmosphere of highly censored political discourse, comments spreading fake news, comments encouraging warmongering and comments derisive of Ukraine have a place within political discourse on China's internet.
That this is permitted a place on the spectrum of acceptable opinion is the point. It's easier to caricature the point by exaggerating it and then disagreeing with the exaggeration.
