I don't think it's disingenuous; I think it's pretty on-the-nose. Also, I think "early exits" are still win conditions at YC; that's one of the (salubrious) benefits of being organized like YC and not DFJ; there's a lot of reasons why a "YC" would want to tune outreach to young people, and none of them need to be "avoid build-to-flip companies".
