You have a choice on which social media platform you wanna post on. The free market will decide which content policy wins. Lets ask some hong kongers how much choice they have.

* China: things you might find "disappear" in discourse include values related to free speech itself, checkered history of the communist party, civil rights, challenges to the authority/policy of the communist party, issues of graft, judicial independence. And political organization/activism to address those issues might get you into trouble where you disappear / are imprisoned or ruined by the state.

* Twitter: you can't deadname trans people, use slurs, or threaten violence (and lots of these aren't tightly enforced). You might get your account deleted and have to create another one if you break these rules often enough.

Can you think of a single worthwhile form of discourse that's forbidden by Twitter itself? What topics are hobbled to the point where society itself is unacceptably held back from the potential progress that would be unleashed if we just let MOAR SPEACH happen on twitter and those whose glorious intellects have been unfairly silenced were finally unleashed?

We're not in US Muslim hate crimes vs China's human rights violations territory, we're in China human rights violations vs the fact that the United States has traffic laws and John Q Citizen gets cranky because he has to actually obey the speed limit damn cops it's a police state grumble grumble. And it does strike me as a bit silly.
