You linked to an article that does not support what you say, as the EFF (who you link to) has repeatedly made clear. Nothing in section 230 requires a platform to be content neutral. It protects publishers who are blatantly biased as well as those that are neutral.

For example, suppose you run a site that is dedicated to getting Republicans elected to office, must of the site content is user comments, and you ban users who criticize Republicans. So you are not content neutral. Section 230 still protects you: if a comment libels someone, the person that posted it, not the site, is legally responsible.
