I don't agreeThey very much do, at least insofar as they can measure this kind of thing (and they can better than us).
For example, I teach friends who want to be DMs a simple way to make their first setting: National archetypes
- The Empire
- The Kingdom
- The Rebellion
- The Republic
- The Theocracy
- The Other One
My point is if WOTC were to do this an perhaps made the Empire majority Dragonborn and the Republic Human and Goliath, and the Theocracy being fiendpact warlock devil worshippers, the plurality of the 2024 5e buying customer base would say that is cool.
