Conservatives want platforms to moderate in a politically neutral way. Passing a law requiring such would be unconstitutional as it would violate the free speech of those companies. Making section 230 conditional upon political neutrality might not be unconstitutional. No Internet platform would ever risk operating without section 230 protections, so they would essentially be forced into political neutrality. So the same effect would be achieved.

Nobody is seriously considering simply removing section 230; that would be devastating to the economy and to free speech both. Any such assertions are no more than sword rattling and idle threats.

Neither is anybody seriously talking about ceasing all moderation entirely. Platforms would become flooded with spam, among other things making them virtually unusable.

Where this all gets very complicated very fast, IMHO, is in how you define political neutrality. And I'll stop here because that's much too long of a discussion to have in a HN comment.
