Describing Shadowlands writing as "disliked" is like describing the Titanic as a boat that got a bit wet. I'm not even saying abandon ship, I'm saying what the intent seems to be like with the Broker retcon to be Ethereals in another plane, or Denathrius escaping a planned death because he was a highlight, and his performance liked by the narrative team. If anything it'd be aligned with the philosophy of "take what works with Shadowlands tie it to the canon people like, recontextualise what you can and memory-hole the rest." This feels perfectly in-line with that philosophy.
Regarding the Edicts:
It's a document where Odyn admits to purging historical records and falsifying narratives to control mortal perception. And you think this disproves the theory that Titans would create false mythology to cover their actions?
The parallel is there if you look:
Reality: Advanced civilization with its own achievements
Titan narrative: "Chaos and misery, pernicious blight"
Method: Purge records, allow no contradictions
Justification: "If you care for mortals, don't lead them astray"
Sound familiar? Let's apply the same template to First Ones:
Reality: Titans violated cosmic boundaries and imposed Order
Titan narrative: "Ancient Progenitors designed everything this way"
Method: Don't mention them in Azerothian records, compartmentalize knowledge
Justification: "Mortals can't handle cosmic complexity"
On Azeroth,
Because it's not a cosmic realm is the exact reason you don't need a Progenitor Lie, it's not violation of another force's
sovereign realm and installation of puppet rulers who dance along to your tune. Azeroth's reality, the material plane. Neutral ground to which none of the six forces have prior claim. The authority on Azeroth is defensible as work of the Titans, you don't have to defer to "cosmic rules" saying "oh yeah, that's just how the cosmos works, is what it is. Sorry about your sovereignity

"
One is trespass you're fudging the record on, one is appearing as benevolent god creator.
