That was a key goal for Orwell’s Newspeak. By limiting the language you can limit the thinking of anyone to only approved thinking.
Also: language as hypocrisy.
"Before creating this Cthulhu RPG we must talk about the "problematic" contents in H.P. Lovecraft work!"
Fine. What do you mean? That his descriptions of Cosmic Horrors are often vague and suggestive so it is difficult for artists to visualise them? That it is truly problematic to stat them or to create rules for people who are afflicted by them? That Lovecraft's poetic leads to a truly deadly game so creating campaigns is problematic and it is best used for one shots?
I MEAN THAT LOVECRAFT WAS A RACIST!!
Then JUST SAY THAT! WHY DON'T YOU JUST SAY THAT?
IMHO, "problematic" entered the wokespeak because... it actually doesn't force you to elaborate an argument. An argument which could be debated into oblivion or even, gasp!, even lead to counterarguments from other wokes, because you either weren't strong enough or accidentally touched a tripwire ("OK, let's concede that in 'The Haunter of the Dark' HPL recognises the values of Italian Immigrants." "You can't devalue racism by implying that someone is only partially racist. Take a month off" - random RPG.net Mod vs. random sane guy).
When someone uses the word "Problematic", the object of the word is in the same position of the main character of Kafka's "The Trial". Asking "What's the problem?" only worsens your position, because "if you don't understand then it only shows how deeply problematic you are". Saying that you are sorry only worsens your position, because "So, you knew that your behaviour was wrong but you persevered anyway." Your friends are then attacked for... just being your friends and accepting your "problematic behaviour". They are next.
But... explaining in detail what the "problem" is? God forbids that the woke attacker risks his skin in an hard debate which goes deeper than the well known superficial screams. And why should the wokes run this risk? You are already condemned anyway.
Other good examples include "Controversial" (there is actually
no controversy: accept that this is wrong and shut up), "Toxic" (usually used when some wokes truly fuck up and people call them out) and "Troubling" (since you mentioned Lovecraft, down with him and his "troubling themes!) I'm sure that it is easy to come up with others.
You can even add "useful shorthand" to "hypocrisy".
"Why do you want to Cancel Lovecraft"?
"Because of his problematic contents!"
"What they are? I mean... do you even read one tale by Lovecraft?"
"No! I won't read the writings of a toxic white supremacist!"
"OK, fine. Oh, I really would want to be one of your neurons... always calm, undisturbed, feed by your body without the need for them to work. What a blissful life your neurons have..."
