The WT has their own WT-speak, and to them 'freeness of speech' means the the glib recitation of the party line. It is NOT freedom of speech in the sense to verbalize what's on your mind; what you really think.
It is ironic that the WT used the US First Amendment right of freedom of speech to defend themselves in numerous lawsuits in the last century. In fact the JW cases helped define US laws and the application of the first amendment and their cases are studied in law schools. But within their own religion they don't apply freedom of speech in the same way. Say the wrong thing and you are penalized.
