The order was triggered by an emergency application from NetChoice, a coalition of online service companies, and the Computer & Communications Industry Association—a group whose members include Google, Facebook, and Twitter—which together argued that the law is “an unprecedented assault on the editorial discretion of private websites” and also a breach of the platforms’ First Amendment rights.
In its emergency application to the Supreme Court, NetChoice and the CCIA argued that the law would “compel platforms to disseminate all sorts of objectionable viewpoints—such as Russia’s propaganda claiming that its invasion of Ukraine is justified, isis propaganda claiming that extremism is warranted, [and] neo-Nazi or KKK screeds denying or supporting the Holocaust.
