Oh it's absolutely terrifying - I just think it's important to highlight that in this situation there's a large power inbalance that doesn't exist in the SV example. It's likely most developers didn't walk into having an App knowing how this weird refund rule worked, so for most folks (if this is an issue) you've got the sunk cost of building the app already and have the choice of 1) putting up with Apple's arbitrary rules or 2) unlisting your app from the store and accepting that you'll never see another dime off your labour.
