Everybody always jumps to Apple’s defense by explaining how iPhones are built for inept users that just want a phone that works with no BS. Therefore, they claim, it’s a good thing that Apple has a highly locked down environment. But what good is this locked down environment if Apple will happily allow scam apps to charge their customers for features the phone already does for free? What’s the difference between a user downloading a scam app from an untrusted source and downloading it directly from the App Store? If Apple is going to have a locked down environment, at the very least, they should make it effective.
