It's all about game theory. Nothing is really absolute - freedom of speech will always have limits. But it's important to tell the people that they do have absolute freedom of speech, otherwise what they have will be gradually eroded by seemingly reasonable steps. For example - you can't speak in favor of terrorist attacks, then a violent protest becomes classed as a terrorist attack, then a protest in which some participants are violent is a violent protest, then any protest might turn violent, then any public meeting which disparages the government becomes classed as a protest. Suddenly, you can't criticize the government, or you're a terrorist. It's far better to say you have absolute freedom of speech, and hope everyone turns a bit of a blind eye when the really crazy stuff gets silenced. That way, if too much stuff is getting banned, people will push back.
