There is a difference between freedom of speech as a cultural concept, and as a legal concept. When most people say "freedom of speech", I doubt they mean it in a specific, literal legal sense, but rather as a vague idea, a general principle. That idea may include corporations being allowed to fire people based on their political views. But when it becomes standard behaviour for people not to mention their political views publicly due to fear of losing their jobs, I doubt that is the kind of society that will have freedom of speech in culture or in working legal sense much longer. Nor do I think that people have such a society in mind when they imagine a "free society".
