Technofeudalism is a term used by Yanis Varoufakis to describe a new economic system that has replaced classical capitalism, based on the control and monetization of data by large technology companies that have evolved into modern feudal lords.

Technology companies have privatized the internet by creating platforms and services that collect and monetize user data. These companies enforce their own rules and use the collected data to increase their wealth and power.

Technofeudalism threatens social democracy because the control and monetization of data by a few large technology companies leads to a concentration of power and wealth that destabilizes social and political structures and enslaves people's minds.
