The premise behind that click bait essay is that Harvard (and a couple other schools), due to their massive endowments can use NIL, filled with endowment dollars to buy their way into the top of major college football.
The issues are a) those schools were once at the top of major college football but they intentionally moved away from that some 90 years ago in order to preserve their academic status (when major football was far less of a threat to that than it is today) and b) it assumes that a school can spend endowment money in any manner it wants. A good amount of this is earmarked for specific purposes and while a few Ivies likely have a larger amount of unencumbered endowment funds than most schools have total endowment funds, there are tax rules on what they can spend endowment money on.
Other than maybe a few dozen alumni from Harvard, Yale and Princeton who at cocktail parties like stating how great their football programs were from the start of college football into the 1930's and how they could get there again, there is really nobody putting any thought or effort into any of the Ivies improving their overall level of play.
