I disagree with the premise of the post. In a year or two, most apps will only support iOS 6. How bad would it be to search for an app you expect, like Facebook or Yelp, only to not find it, not having any indication of error? At least this way, people realize that they have to buy a new iProduct to use an app. Having an empty app store and not knowing why is way worse than being teased by apps you can't get.
