At the risk of not piling on to the Apple dislike here, if you use a non-Apple payment system, and you have an issue, you now need to go to the specific company and payment system, you can no longer demand your money back by dealing with a single company. I presume even more scam apps will take your money and ignore your complaints; imagine trying to sue a company in some foreign country to try to get your money back if they stole it. When Apple controlled the payment system, Apple could be sued in your home country. Of course this happens on the web too, but apps on your phone very different from web apps.
