It appears the conversation is mincing terms between freedom of speech (a legal principle that guarantees some limited rights regarding ones ability to say certain things) and the idea of "expressing yourself freely" which is a more encompassing terminology that demosthenes appeared to be addressing. Providing freedom of speech does not mean, necessarily, that you are providing one the complete ability to "express themselves freely". Thats ok, they didnt (nor me) appear to be saying that limitation is a bad thing, but only pointing out they are not equivalent terms.
