Is it though?
Its a requirement...you dont have to follow it and can find another institution. They are doing what they have decided is best for the student body, faculty and community.
If one wishes to continue their studies at Yale, they have the choice to comply. If not, they can apply and finish studies elsewhere. In the end, the only folks really getting the short end would be Yale with depressed enrollment. That remains to be seen.
Again, its easy to critique when you arent the decision maker and dont have all of the information they are privy to.
And im not agreeing or disagreeing in either sense. Just giving you an alternate viewpoint.
