Given that every government in history which has recognized the concept of "free speech", including the United States, has regulated and even outlawed some forms of speech, and given that "consequence" is a natural, emergent property of societies and the fact that humans are social, emotional animals who don't process speech as mere passive data, one must come to the conclusion that free speech has never existed at any point in space or time.
That being the case, one wonders why everyone is so concerned now about something that, clearly, humanity has never needed up until this point?
