Freedom of speech is a principle that transcends political policies. In theory, it is a clear and unambiguous concept; in practice, governments ruin it with nearly arbitrary rules that run counter to that fundamental principle.
There are plenty of exceptions to freedom of speech in countries I'm familiar with. Things like advocacy of terrorism, hate speech, threats, disturbing the peace, obscenity in public, blasphemy, pornography of certain kinds, providing financial advice without a license, leaking secrets, copyright.
Edit: fraud, incitement. Who knows how many others?
