I don’t think anybody cares what Nobel’s family member’s protests were about. Does anyone even bother to learn their names or know a single thing about their lives? It’s also not “fake” and the university didn’t invent it.

The point is there is a prize that many/most people agree is one of the top recognitions of achievement for the field. Whether you call it Nobel or something else, doesn’t change a thing for anyone, as long as the prize is well known and well regarded.
