UPDATE: The Constitutional lawyer replied:
Thanks for your note. I’m rather ambivalent about Section 230 which was needed when adopted far more than now. I don’t view as censorship every decision by a social media entity not to carry some posted material. Editing is what every newspaper does as is simply selecting what to print. Social media is in many significant ways different but in others the same. So I think some decisions by social media not to carry everything posted—false statements about medicines, for example—but sometimes unfortunate.
