>>58623453To be precise, it's spite towards Masuda, especially now that we know that GS is the result of his assertive takeover after Tajiri gave up.
This is also why Hoenn got ruined by Ohmori's waifushit, Sinnoh got ruined by empty tech demo fields and a dogshit "remake" that's more of a port, and Unova isn't ever being revisited and instead had its contents stuffed into those empty tech demo fields and a SV DLC that takes place in "Unova, but not really".
Note how much more reverence LZA shows towards Kalos, at least the parts of things that Masuda likely didn't have a hand in. Come time for Legends: Galar, you're going to see an extremely different tune be played when it comes to redeeming the Galar region.
