Explaining that your app has to be installed differently (and why) is going to be a rather thankless task. Anyone who plans on going this route should start working on their phrasing now. I recommend not blaming Apple, but boasting about the advantages of your approach. “Hand-crafted uniques”, not “Down with Walmart”. Make customers feel good about their purchase, not bad about the world.
