So you're saying Google is doing fuck all to protect customers on their already locked down store, right? This doesn't sound like it will be addressed by Google extending developer registration outside of their store at all if they can't even address obvious scam apps that they're already promoting. And to your point, yes, Apple probably does do a better job of maintaining their app store, that way they can prevent some of the push back on iOS being so locked down. An iPhone sounds like the right device for your father.
