It's definitely not a truthful retrospective of a failed ad (I would be shocked to hear that they were actually going out of business), but it is made to follow the style of one. However, it's simply using that form as a vehicle, not mocking or shaming the subjects of the imitation, so I wouldn't describe it as satire. Perhaps irony, verging on sarcasm? The ad and the article are part of a single, original marketing campaign, done very much in their style: part spectacular and part absurd.
