Section 230 is from 1996. For reference myspace launched in 2003. It has been modified since, but not in a way relative to this discussion. Section 230 classifies providers such as Facebook and Twitter as "interactive computer services" and not "information content providers." This protects them from lawsuits based on the content they provide.
I'm not arguing that Facebook should be held to the same standard as the person who creates the content. However, when Facebook services misinformation on COVID with negligent moderation or even intentional promotion, or they allow eighty thousand posts by Russian Internet Research Agency (IRA)-controlled accounts in two years near an election, reaching 126 million users [1 (Mueller Report)], maybe there needs to be some amendment. Perhaps not completely recategorizing Facebook, but adding some more responsibilities on these major platforms to at least not promote bad information, polarizing content, and information campaigns from foreign governments. When I did some research into how to disincentivize social media companies from spreading misinformation, reforming 230 was the best option I saw.
Edit: I posted a more detailed version of this elsewhere on this thread to provide more background. Then I realized I couldn't delete this abridged version.
