First and foremost congratulations on your daughter!! No easy accomplishment getting accepted but even more commendable that she appears to have taken full advantage of the opportunity.
While I find those responsible for Columbia’s seeming deceptions to be unethical and despicable I don’t think students were meaningfully harmed.
As an analogy, if I go to a restaurant based on numerous positive YELP reviews and thoroughly enjoyed the meal, I wouldn’t view myself as harmed if I later found out the reviews were self written. Would it cause me to question the owners ethics absolutely. But I go to a restaurant hoping to find a good chef and wait staff not a moral owner.
I think undoubtedly there are some culpable administrators at Columbia but the students who attended got exactly what they expected and paid for in the form of a world class education.
