Governments use censorship to control political narratives by suppressing information that contradicts their agendas or threatens stability. This can involve restricting access to media, altering public messages, or surveilling dissidents to silence opposition. By controlling the flow of information, governments can shape public perception and prevent dissent, thereby maintaining their authority. Censorship often escalates during times of crisis, where governments may justify their actions as necessary for national security. However, pervasive censorship can lead to public backlash and undermine trust in the regime.
