What country limits free speech?

Many countries impose limitations on free speech, often citing reasons such as national security, public order, or protection of social harmony. For example, China has strict regulations on speech, including heavy censorship of the internet and media, to maintain control over public discourse and suppress dissent. Similarly, countries like North Korea and Iran have extensive laws that restrict free expression and punish those who criticize the government. These limitations often lead to widespread human rights concerns and calls for greater freedoms.
