There is, in principle, no difference between controlling what people are allowed to say and controlling what people are allowed to hear, including controlling any middlemen who are involved in propagating speech.
In the USSR, you could say what you wanted inside your own home, to your own family, but were you to speak it where others could hear it, or publish it so others could read and share it...
So, no, you are wrong: the ideas are not different at all, and if you are against one, you are against the other. You judge yourself to be worthy of deciding what others are allowed to hear. Would you allow me to judge what you are allowed to hear? If you would, I would feed you a steady diet of history and philosophy until you discarded such ideas, ideas which enabled much oppression and suffering in the 20th century.
