I'm not sure what you're trying to say here. They were not "removed", they were made to be disallowed if and only if the school wanted to receive a certain kind of government funding. Some schools have enough money that they can ignore this. Notably, Stanford said they would give up the funding to keep their policy of legacy admissions.

So the richest, most prestigious schools where legacy admissions are a gateway to the upper classes, will keep the policy.
