The article also condemns France for arresting supporters of the recent, random ISIS attacks, and, I think, for arresting supporters of the Charlie Hebdo attacks. (I gave up on it before then, not really wanting to be reading the moral equivalent of Stormfront.org.) What the headline means by "free speech" is "anti-Semitism and support for terrorism"; if I had the karma to do it, I'd flag this. I'm not, personally, very fond of free speech as a moral principle; but I think that those who are, should feel no contradiction in saying that they support free speech, yet silencing calls to genocide against highly vulnerable minorities.
From the name, _The Intercept_ is probably an extreme left-wing magazine, and yet this article would fit in on an extreme right-wing website. Extremes meet, and that's how you get neo-Nazi content on Hacker News.
