As the other comment mentions, restrictions like those may well be overturned, but it's true that free speech is not an absolute right within the U.S., considering we have laws against slander, libel, divulging personally-identifiable information and some types of medical records, espionage, etc. Free speech is an individual right that like any other right, gets balanced against others' individual rights.
