As I have written in the past I have no problem with the New York Islanders keeping their iconic logo which has been changed from darker blue/orange to a logo with four stripes.
Few noted the changes.
Often the hypocrisy has been written about here regarding media/teams as the New Jersey football teams (and the Red Bull) market themselves as New York, and the media/teams will not starting calling the Mets Queens or Yankees Bronx, or the Manhattan teams with their generic logo's which never included a map.
No matter where the Cosmos call home (when operating) they have always called themselves New York.
