Think of it as a cargo cult of language; play-acting at meaning-saying: Language wielded like a ritual dagger instead of a tool.
You can recognize some examples of what he'd complain about if you pay attention to that sense. I'm annoyed by lots of uses of English; I must be fun to be around. I can't say they're misuses, but i dislike them. My favorite might be "I would argue", followed by... the author making an argument? Why the distancing? It's a verbal tick. It creates an air of passivity or detachment which is immediately contradicted by the words that follow. I suppose there's an idea these days that being detached and emotionless confers objectivity and wisdom, but I can't say i know at all for certain why people write or speak the way they do.
Language should stick to meaning like muscle to bone.

I would argue Orwell would definitely get downvoted all the time on HN for saying clearly his opinion and not masquerading it in an etiquette of apparent self-doubt. ;)
I really like his essay on politics and language, thanks for the reminder.
