No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.
[Section 230] has allowed for YouTube and Vimeo users to upload their own videos, Amazon and Yelp to offer countless user reviews, craigslist to host classified ads, and Facebook and Twitter to offer social networking to hundreds of millions of Internet users. Given the sheer size of user-generated websites (for example, Facebook alone has more than 1 billion users, and YouTube users upload 100 hours of video every minute), it would be infeasible for online intermediaries to prevent objectionable content from cropping up on their site. Rather than face potential liability for their users' actions, most would likely not host any user content at all or would need to protect themselves by being actively engaged in censoring what we say, what we see, and what we do online. In short, CDA 230 is perhaps the most influential law to protect the kind of innovation that has allowed the Internet to thrive since 1996.
Does the Constitution require Americans to accept Big Tech censorship? The claim is counterintuitive but the logic is clear: If you submit a letter to this newspaper, the editors have no legal obligation to publish it, and a statute requiring them to do so would be struck down as a violation of the Journal’s First Amendment rights. Facebook and Twitter, the argument goes, have the same right not to provide a platform to views they find objectionable.
