True, though there is much emphasis placed on the link between language and thought in the book. As the parent comment suggests, there is a lot of tacit differentiation-without-distinction when it comes to issues of privacy, censorship, and governance.

I guess double-think is nothing more than an extreme form of cognitive dissonance being accepted by the masses, the interesting part is how this achieve in the book. Again, language & propaganda come first, then information control, followed by swift and brutal violence for dissidents.
