But the US wins big on freedom of speech. Almost no other country protects free speech as well as the US does (flawed as it is) and that's not a stupid measure.
I don't necessarily agree with you that an American more freedom of speech than say, a British person. But assuming it is, well, US: 1 (freedom of speech), Europe: 10 (for all the other nonsense illegalities in the US).
P.S: It is quite ironic you are saying the US wins big on freedom of speech in a thread on this article. Not saying that a European state wouldn't do the same to a whistleblower (many wouldn't though; especially Scandinavian countries), but even if they would, the governments didn't put themselves in that situation in the first place.
Is the US the most free country in the world by every measure? Of course not. Overall is it one of the most free or the most free? I would say yes.
