I think that choices like this come from a weird symbiotic relationship between UI designers and product managers. The UI people need to justify their jobs; if they sit on their hands all day because the UI works well, they can't make that justification. Managers don't want to "see a product stagnate" and to fix that they want a "fresh new look". The users don't enter into this relationship.
