In an era where digital technology serves as both a tool for liberation and a threat to democracy, the term “digital authoritarianism” has emerged to describe the strategies employed by authoritarian regimes to exert control in the digital sphere. This chapter explores the defining characteristics of digital authoritarianism as exemplified by countries such as China and Russia, identifying three primary pillars: information control, mass surveillance, and the creation of a fragmented, isolated Internet. Furthermore, this chapter emphasizes that digital authoritarian practices are not confined to authoritarian regimes. Democratic governments and technologically advanced private corporations, especially the dominant tech companies shaping the modern Internet, are also capable of adopting authoritarian tactics. Finally, the chapter argues that the technology itself—through the omnipotence of code in cyberspace—may inherently foster a form of digital authoritarianism.
