Having free speech has nothing to do with having no consequences to what you say. Sure In some instances there might be overreaction and especially companies prefer to be on the safe side of social discourse. The issue there is not free speech but workers rights (in the US at least). But that does not limit your free speech, you’re still free to say and publish it. But nobody is required to actually listen to it, or publish it for you. Just because we are free to say what we want, does not make all opinions equal in worth.
