Fine. I can defend that private enterprise point as well. I agree with much of it but I'm also concerned with free speech being stopped. So let's just take away their protection from lawsuits if they want to play politics. Let them play in the marketplace like everyone else and be exposed to lawsuits just like everyone else.
You're badly confused and ill-informed in proposing something that would DECREASE free speech
not increase it. It isn't just social media companies that are largely (but not completely) defended (not protected) from liability for user postings and messages. Section 230 is a law that dates back to 1996—long before Facebook, Twitter, and other social media companies existed. It offers strong defense to lawsuits for
every online news site, website, message board, forum, etc.—including this one—from lawsuits over user generated and other third-party content that is posted or linked to their site. Please note that the law does
not protect a service or website from being sued or prohibit anyone from filing a lawsuit—but the law does provide a strong defense to such lawsuits.
Because Section 230 exists, online service and content providers can feel relatively safe in allowing user commentary on their content; forums like this can exist; and social media platforms can provide users with the ability to publicly express themselves; with some confidence that if they are sued for that user generated content, they will have a strong defense.
Without that defense, online sites and services would likely eliminate user comments completely or moderate them much more heavily in order to limit exposure to liability and a vastly greater number of potential lawsuits. The result would likely be much more limited opportunities for public expression online.
