This kind of stuff is one reason why it should be illegal for platforms to censor at will, it should be possible to sue them for censoring stuff they shouldn't be censoring just as it is for not censoring stuff they should be censoring. No matter how much they like to say they are fReEEeE pRiVAte eNTErpRiSes, they provide de-facto public spaces(public as in accessible to the broad public, not as in government-run) and should be treated as such. They shouldn't have the power to be legislative and judiciary of public communication.
