Okay so Youtube started recommending these videos in a genre called "HFY" or "Humanity Fuck Yeah" which, as far as I can tell, involves AI narrators reading AI-generated stories over slideshows of AI-generated images and the stories are all military sci-fi where humans are the bestest warriors the galaxy has ever seen and kill stupid evil caricature aliens 1000:1. Once in a while there's a story where an alien race does a massacre to humans which gives the humans an excuse to gloriously commit righteous genocide
Why is this a thing
Who asked for it
Who's watching it
Bet there will be shit like avatar but the humans are somehow the goos guys and the unobtanium is needed for humans to survive despite them fucking up another planet.
If you were to dig far enough back into r/HFY's history you would absolutely find that, yes. Like I'm not even guessing here, I am 100% confident that literally that exact fanfic is somewhere in the depths there, right alongside memes of the one officer lifting weights captioned with a particular rant that I can't remember if it was a quote from the movie or 40k inspired fanwank.
Like the WH40k flavored contrarian reaction to Avatar was 100% part of the genesis of that genre and that sub.
I had the misfortune of seeing that exact image and can confirm it wasn't in the movie. It's also completely at odds with the character it's posted next to, who's a stereotypical dumb violent meathead (so accurate portrayal of an American troop)
