Ok, here's a real life example then. My parents were on Skype to me today, and my Dad was talking about some controversial topic or another - a couple of times my mum said "you can't say that over the internet, people are listening".
Furthermore I actually disagree that self censorship is the key component of an Orwellian society. I think surveillance itself is the key component. Reading the interpretation below I challenge you to deny that the US and many other governments aren't well on their way to the dystopia described by Orwell.
Police charging through your house without permission whist you sit back and say 'they are just doing their job' is the epitome of an Orwellian society.
