He may be right that people self sensor to keep a clean image of themselves in the eyes of their peers, but Orwell did not live in a time of cell phones.

If you people still don't believe you're all under deep surveillance, after Assange and Snowden leaks, then you all are mentally ill.

We now know that this government is willing to subvert the first amendment by forcing shadowbans. Orwell's books doesn't come anywhere near what the current government does. Just because you all aren't in interment camps now doesn't mean they won't use the data they gather to be used against you in the future.

So now people that want to speak their minds are either censored by the sheep that downvote or the government that forces censorship.
