The hyperbolic hand-wringing whenever the App Store is discussed really cracks me up. We get lots of nonsense comparisons to brick and mortar retail and their markups. There's endless pearl clutching over the potential for malware. There are more nonsense comparisons to Nintendo or Sony or whatever. There's the childish "go build your own smartphone if you don't like it" sentiment. It's hilarious.
Allowing additional App Stores and side-loading will have no impact on security. Nothing will prevent a user from only using Apple's App Store. Problem solved. Now if a developer decides to take his or her app to another App Store, the user will have to make a decision. Will his or her irrational fear of using a non-Apple App Store win? Only the user can decide. But let's get real. We've all been doing that for decades on the Mac and there isn't a tsunami of malware.
Furthermore, the possibility that someone might download malware isn't MY problem. I don't need Apple or any other entity to nanny me. Besides, there have been repeated cases of scams and apps with malware making it through Apple's review process. This is well documented. So Apple's App Store isn't guaranteed to be free of malware either.
Comparing the iOS market to Nintendo or Sony or Xbox is also a totally specious argument. At this point, iOS is a platform, not a product. When you reach that level of ubiquity, you're going to be scrutinized through a different lens. That's just reality. There should be a different level of scrutiny when billions of people rely on your product.
Personally I don't have a problem with Apple's commission. My problem is with their gatekeeper status. They decide what apps their customers can ultimately use. If the Chinese government tells them to pull thousands of apps from the App Store, they oblige. This is dangerous and, in my opinion, morally unacceptable. Thankfully more and more governments around the world are pushing back on Big Tech Tyranny. No amount of hand-wringing and FUD is going to stop the inevitable dismantling of the App Store monopoly.
