While that certainly was the theme, the sticking point for most people is the fact that the Unsundered were ignorant of what they were actually facing, even after building god.

That, and as far as they were concerned with a history we never get to see, the past for them was the pinnacle of what any society could hope to attain. It's more or less, why embrace change if the change is for the worse? In every way? Do people who break their legs not go through physical therapy to ensure that they will walk again, if their wounds can heal to that degree?

So, the problem isn't with the theme. The problem is with how the theme was delivered.

Meteion broke the Ancients' legs, but Venat noticed they could still fly. Instead of telling them who broke their legs, and helping them to fight her, she clipped their wings and broke them further. She forced them out of upright posture to be animals, obsessed only with the instinct for survival.

Rather than delivering the theme gracefully, eloquently, expertly... it was delivered within a psychotic fever dream. What we actually get delivered to us in Endwalker is the word that Thancred willed out with his last moment, the clarion call of his soul, "Survive."
