"Popular tech companies—Google, Facebook, Twitter, and others—have strongly protected free speech online, a policy widely associated with the legal norms of the United States. American tech companies, however, operate globally, and their platforms are subject to regulation by the European Union, whose member states offer less protection to expression than does the United States. European regulators are pressuring tech companies to control and suppress extreme speech. The regulators’ clear warning is that, if the companies do not comply “voluntarily,” they will face harsher laws and potential liability. This regulatory effort runs the risk of censorship creep, whereby a wide array of protected speech, including political criticism and newsworthy content, may end up being removed from online platforms on a global scale."
