Index on Censorship is an organization that works to protect freedom of speech and expression by defending people’s right to speak out and share their ideas without fear of being punished. They do this by monitoring government censorship, raising awareness of the importance of freedom of expression, and helping people stand up against censorship when it happens. They also provide legal and practical support to people who face censorship. By doing this, they help to keep censorship from taking away people’s right to speak up and share their ideas.
