It's the calls to action by the tinfoil hat crowd that is problematic and most typically why platforms shut down their posts. The buried lede in most stories about censorship on social media is the people getting posts removed weren't just spouting tinfoil hat theories but were directly or indirectly calling for violence or harassment of certain ethnic groups. A veiled or coded call for violence is still a call for violence.
Social media, no matter stupid claims to the contrary, is not a public forum or town square. It's owned by private interests. It may be publicly available but it is not owned and operated by the public.
Private platforms don't usually want to amplify racist dog whistles or other coded rhetoric when they've been made aware of it. Attention seekers love when they get censored because they can run to another platform to complain they got censored for claiming COVID leaked from a lab but not the follow up post where they used that as justification for torching an Asian market.
