content: RTFA  Section 230 of the Communications Decency Act immunizes online platforms for their users’ defamatory, fraudulent, or otherwise unlawful content. Congress granted this extraordinary benefit to facilitate “forum[s] for a true diversity of political discourse.” This exemption from standard libel law is extremely valuable to the companies that enjoy its protection, such as Google, Facebook, and Twitter, but they only got it because it was assumed that they would operate as impartial, open channels of communication—not curators of acceptable opinion.
