That hatred is more widespread than people might think, and extends beyond DEI reasons. For instance, I'm pretty sure Aonuma and Miyamoto hate their old NES and SNES era games, based on how Nintendo treats certain franchises.
In the entertainment business, you're competing against your previous works. You become your own enemy. An aging rock star who despises playing his band's greatest hits is a well known story, or the typecast actor who cannot seem to land any roles outside of their breakout character. I don't see why it would be any different for legacy videogame companies with franchises that are 20+ years old.
I think there are plenty of modern devs who are offended by their older franchises and see it as an excuse to drown it in DEI, but I think there are other devs who are sick of making games in someone else's popular franchise because it doesn't allow them to "tell their own story" (or whatever).
