What does freedom of speech prevent the government from doing?

Freedom of speech prevents the government from censoring or punishing individuals for expressing their opinions, beliefs, or criticism. It safeguards the right to speak freely without fear of retribution, thereby promoting open discourse and debate in society. This principle also restricts the government from interfering with the press, allowing for the dissemination of diverse viewpoints and information. Ultimately, it protects individuals' rights to advocate for change and hold authorities accountable.
