Leftists went from "their mocking you chud" to "they're secondaries who don't know the fluff" at astonishing speed

I don't need the Space King guys to get into it in their funny video, but what I would really like to see the "media literacy" people contend with is that the Imperium are the good guys because
GW writes the Imperium as the good guys all the fucking time. Particularly in their Black Library stories, which are usually what people talk about when it comes to lore discussions, more so than whatever gets put into the various game books. Compare people's knowledge of the Horus Heresy novels to the lore that gets written in the Black Books and all the 30k game books since, plenty of which is never covered in novelization.
Regardless of the famously grimdark setting, people want to read stories about heroes and villains. So that's exactly what Black Library gives them, heroic protagonists battling against the worst people you can imagine, unspeakable horrors, and an abundance of existential threats to humanity. Even stories starring CSM and Traitor Legions seem to habitually have protagonists that are relatively nicer than their usual lot, even if it's just while they're story protagonists. Within the Horus Heresy, think of Argel Tal, Kharn, Sevatar, Argonis, Perturabo (Angel Exterminatus), and Mortarion (The Buried Dagger). Evil douchebag protagonists are often regulated to short stories where their douchiness can be tolerated by readers in short spurts.
Captain Lieutenant Captain Titus, the new brand ambassador of 40k, is a big damn hero. Roboute Guilliman, ruler of the Imperium, is a hero who's doing the best he can. That's what true "media literacy" imparts.
On one last note, I find it curious that the Black Library stories of conquests in the Great Crusade tend to be about genuinely liberating human civilizations from monstrous aliens that prey on them. Even when it comes to the Interex of Horus Rising, the tragedy everyone knows of peaceful coexistence with aliens that could have been if it wasn't for that douchebag Erebus, it has to be considered that the aliens in question
were a subversion on behalf of Chaos. That's why they had that Chaos sword.
