How has freedom of speech changed over time?

Freedom of speech has evolved over time due to the changing societal norms, legal decisions, and technological advancements. While there have been landmark cases that have expanded protections for free speech, there have also been challenges such as hate speech and disinformation that have called into question the boundaries of free expression. The internet and social media have further complicated the landscape by providing platforms for individuals to express themselves but also raising concerns about censorship, misinformation, and online harassment.
