If anything, I wish that the phenomenon Orwell is describing would be used by the people on the "right" side more often--but people who are doing what they think is right don't as often feel the need to obfuscate it for PR purposes.
Ultimately I think understanding the phenomenon Orwell describes is fundamental. You should be able to read "Two died after a shooting incident involving LAPD officers" and know to look further to discover that meant "LAPD shot and killed two unarmed black men". But actually following Orwell's advice on how to write puts you at a disadvantage. Playing by the rules when your opponents aren't is a fool's game.
