Many "liberal governments" of the West certainly have some authoritarian elements to them. I don't see that as a conflict with advocating for free speech. If the government is running the propaganda, who is supposed to push against that other than dissidents protected by free speech? It certainly won't be the government or "the authorities".

I don't understand what "YOLO anyone should say whatever and never face rhetorical consequences" means. Who should be enforcing these consequences? What even is a "rhetorical consequence"?

As ever, the problem with creating an authority to regulate what is truth, is who is going to be that authority, and how are we going to prevent it from being corrupted by human nature.
