That is not true. Freedom of Speech has always had costs. If your speech harms people, you are free to say it, but you can be held civilly or criminally liable for that harm. It's the old "Shouting FIRE in a crowded theater" legal doctrine. I think speech that costs you money or your freedom can't really be called "free". Inciting riots is "free speech", but all the courts have upheld laws punishing people for doing that.

Claiming the First Amendment allows any speech is like saying it's a free country, so swinging your fist is protected. But only until it hits me in the face: Then it's a prosecutable crime.
