Today, Trump managed to run up against the ramifications of his EO that I predicted yesterday. He quoted some police chief who was on the wrong side of the race riots back in the late 60’s. While his message was first just locked so others couldn’t interact with it (censorship, but not censoring him), my understanding is that the thing is now hidden. Which is censorship. Censorship that is more or less required if the Section 230 exception doesn’t apply to Twitter.
Twitter isn’t responsible for the content users post on their site. The social media business model becomes untenable if they’ve got to employ people and technology to police content sufficiently to minimize legal risk. If they are responsible for content posted on their site, then, yeah, they need to hide/delete posts inciting violence, libelous information, and a whole lot of other data they’ve been allowing to fly. Content that makes up a good bit of Trump’s Twitter usage.
