It's like the evil [character] meme where an image of them was inverted, along with a caption of something that's the opposite of what they'd say. So, here dystopia is basically depicted as "evil utopia"

I think it's just the utopia image with colors inverted, which is a visual gag that I'm loving

it is actually how the exploit was found

The XZ exploit was found because some dude was investigating performance issues in a system, and noticed an unusual amount of time being spent in SSH processing, IIRC.
