I don't think people using Android are different from those using iOS and recognise that that most popular alternative 'store' for Android does not seem to fall victim to these problems. This is very much related to the fact that F-Droid only hosts free software but the same thing could be done for iOS if Apple lifted its heavy control over the platform and its users. I see no reason why a similar free software store for iOS would turn into a scumware-infested hell hole.
