Chomsky's an anarchist so your point is correct. I believe what he is referring to is a hierarchical society with a strong component of freedom of speech (which he supports). In such a society, the elite have to control thought in a different kind of way. In Chomsky's anarchist society, there would be no elite, hence no class that needed to control thought.
Dictatorships don't need knowledge. Capitalist democracies do, hence knowledge must be molded in those societies so the elite live a justified existence.
