The Shifting Landscape of Global Internet Censorship: An Update in Communications Encryption is Tempered by Increasing Pressure on Major Platform Providers; Governments Expand Content Restriction Tactics

"This study, conducted by the Internet Monitor project at the Berkman Klein Center for Internet & Society, documents the practice of Internet censorship around the world through empirical testing in 45 countries of the availability of 2,046 of the world’s most-trafficked and influential websites, plus additional country-specific websites. The study finds evidence of filtering in 26 countries across four broad content themes: political, social, topics related to conflict and security, and Internet tools (a term that includes censorship circumvention tools as well as social media platforms). The majority of countries that censor content do so across all four themes, although the depth of the filtering varies."
