I realize this is Apple's argument but it's also completely specious for the simple reason that Apple has a conflict of interest. They see the App Store as a revenue stream which means they are much more incentivized to protect that revenue stream than to protect their customers. The App Store has become a protection racket. "Nice app you have there. Be a shame if something were to happen to it." The only practical way to fix this is the way all protection rackets are fixed: The government comes in and says "Stop this or we put you in jail."
