I think it's a big (and likely incorrect) assumption that all of (or even a plurality of) the people making these comments working in admissions are themselves white.
It's not just that they're not representative of an entire group of people, many aren't members of that group at all.
It's also not necessarily entirely on the admissions people - the argument made in that substack (and ultimately the conclusion of SCOTUS) is that affirmative action is a euphemism for racial discrimination.
Ultimately you have to be doing something like this somewhere if that's the policy since that's explicitly what it means, the internal comms just show the reality of the policy that's often not said in public communication (because imo it seems obviously bad to most people).
