If you're worried about overreach of government control, i.e. what these books are actually about, there's a nice thread about Edward Snowden also currently on the front page. Apple, Criterion Collection, etc., have relatively little control over our day to day lives.
I disagree that those books are only about government control. Censorship can come from anyone who controls the distribution of information, and these books are still relevant when talking about the consequences of censorship.
