This is new: Censoring email.
Some time ago I commented that our private emails had become a target of surveillance. I remember saying it, because the response was perplexing to me: No one cared or considered it remarkable. One person even said she had nothing to hide, so mox nix.
Similarly, I have posted from time to time about censorship in media, only to be told that the free flow of information is as good or better than it has ever been. Nothing to see here.
It seems we have arrived at the next stage: Active control of things we can say to one another at a personal level, privately. The direction things are going is both clear and sinister.
