Because it has nothing to do with what Obama did. Any country has the right to decide who they accept on their soil or not. But only authoritarians remove that right at the stroke of a pen without due process to those who have obtained it legally and have never committed a crime. Essentially, what the administration is saying now is that it doesn't matter if a person has a certain right granted to them in accordance to the law, this right can be removed unilaterally by the President. If you don't care about that, wait until they come for you or your family.
