Removing the WTC from films

Recently, I read a review of "Zoolander" in which it was stated that the World Trade Center towers were digitally removed from the New York Skyline. Do you think that this should be done? After all, when this movie was made, they were there.

Granted, any movie that claims itself to be set after 11 Sep 2001 should not have the towers, but do you agree with T.V. shows and movies digitally removing them from previously shot footage?
