Singapore Airlines has been doing (used to do?) do this for ages: "GV2" was a Great Value fare for 2 people, "GV4" for 4. I also don't find this particularly outrageous. Lots of companies do volume discounts, and traveling as a family gets very expensive very fast. Finally, the fare bucket system used to price flights usually works the other way to penalize groups. If there's 3 seats left in the cheapest bucket, and you try to book for 4, you don't get 3 cheapest plus 1 more expensive, your entire group gets priced at the more expensive bucket.
