Quackery in what sense? It is my understanding that to be a quack in a legal sense one must first be a licensed doctor, and malpractice is covered by freedom of speech. But you referred to celebrities practicing "quackery" which I assume means that they were saying the same nonsense that could get a doctor's license pulled, and that is absolutely covered by freedom of speech.
Also, you have already admitted there is a Ministry of Truth equivalent, as such a thing is necessary to prosecute people for telling lies.
