There is something chillingly unconvincing about their attempts at informality. Big Brother jokey is a lot more frightening than Big Brother bureaucratic or Big Brother bombastic. Too bad this insight wasn't available to Orwell or he could have made 1984 even scarier.
I don't think there is any attempt at anything. It's just written by someone not very intelligent supervised by someone of similar intelligence swimming in a sea of mediocrity.
This is my estimation of the situation.
A Hanlon's Razor moment: Never attribute to malice that which is adequately explained by stupidity.
