By modeling their new ads on Apple's campaign (and even coming up with a Hodgman clone) Microsoft firmly admitted defeat. You don't run a winning ad campaign like this.
As for bitterness, I guess I feel for the fellow developers at Microsoft. There are many extremely talented and creative engineers at MS, but imagine how bitter they must be feeling right now as they see their genuine efforts being turned into tuЯd by hordes
of incompetent nincompoops in MS marketing and management.
