U.S. has done the same during times of national stress, Sedition Act of 1918 for one (repealed in the 1920's). Hate speech not protected by the First Amendment, some point to the Espionage Act of 1917, which is still on the books as 'chilling of free speech' with regards to whistle-blowers and others who "leak" information.
The U.S. has many censorship laws on the books and has had some enacted from time to time to squash certain types of speech or activities (McCarthy era for one). We're not as lily-white as you may think in this area.
Certainly the U.S. is not anywhere near the position detailed in your link, at least not today. But who knows what tomorrow may bring?
Those two acts were passed in a time of war and were still wrong. Brandenberg vs. Ohio showed these would never pass Constitutional muster today. Heck the riots and protests of the 60's proved that. And Europe is not in a World War situation. The EU is afraid of two politicians and want to take away some parts of their rhetoric to protect themselves, their power and their bureaucracy.
Congress repealed the Sedition Act in 1920 before it could be challenged in court, as you noted. Hate speech is protected by the First Amendment, not sure where you are getting your information.

The only place I can find today that threatens free speech is on college campuses, liberal bastions.
No doubt we have had periods of time (e.g. WWI) where free speech was tested, but SCOTUS has defined pretty finite instances where free speech can be limited (e.g. fighting words).
Whistle blowers have special protections if they follow the steps outlined by Congress. Exposing national secrets is a crime and should be a crime.
