Not every issue where speech is limited is an issue of free speech. If you're told that you can not write on my house's wall, it's about speech, but not issue of free speech because it's my house and I decide who writes on it. If a mafia boss is imprisoned for ordering a contract murder, it's not issue of free speech, because even though the order was spoken, the murder is the crime that is punished, not speech. If you are not allowed to talk in the movie theater while movie is screening, it is not an issue of free speech - it's the issue of it being not the right place to speak. If there's a trade embargo that prohibits providing services to nationals of Elbonia and an Elbonian can't publish her speech - it's not the issue of free speech because the issue here is the embargo, not the speech. Having "speech" somewhere in the picture does not automatically makes it an issue of free speech. The same speech would be easily published if produced by anybody else. There's no issue with the content of the speech.
