What is the goal of state internet censorship, and what determines how capable a censor is?

The goal is to prevent or limit the spread of information inconvenient to those in power; capability scales with the censor's budget and expertise.

The goal: stop or limit the dissemination of information and knowledge that the relevant authorities find undesirable — often critical reporting, opposition voices, or information about human-rights abuses.

The method: implement technical measures, especially against content and resources outside the actor's control — foreign media, governments-in-exile, opposition organisations, and fringe groups.

The resources: technical means and expertise depend heavily on the actor. Authoritarian states invest millions in censorship infrastructure, while smaller actors fall back on commercial filtering solutions.

Tip: Censorship is an arms race funded by budgets — which is why circumvention tools aim to make censorship expensive, not just technically possible.
