For anyone curious, 230 was created in response to Prodigy getting dinged for reasonable (by that era) moderations standards when something they left up was considered libelous, and Compuserv, who opted to not touch anything was in the clear.
230 was created to encourage moderation. Without it, things like Usenet would have been shut down at many universities.
Without something like 230 anything that enables user content would be in a catch 22, if you edit posts you are a 'publisher', but if you leave up horrible material (think illegal material) are you at risk of having legal risk as a 'distributor'.
Its not perfect, all of the negative things attributed to it have some truth. For example, aggressive algorithmic content presentation may not exist without the 230 protections. Its not a hard case to make that choosing content in any fashion other than chronological is publishing.
I'll also through in an addition, 230 does not cover distribution, a point made by Clarence Thomas in a ruling not too long ago. I'm surprised that there haven't been more cases against companies for their role in distribution since its been reasonably demonstrated that they "know" what content is fairly well by their own tools. Were I at a firm or an AG office, I would push to make this case.
