It is the blog post @MereCivilian has linked to (you can find the link in the first post of this topic).
Apart from that, Jason Snell, John Gruber, Rene Ritchie and others have talked and written about this topic (oh, boy, this will get me into trouble again 
).
Just to be clear: I am happy with iOS and the apps that are available to me. I am also fine with the pricing structure (I do not think that āAndroid pricesā or āfreeā are the way to go, a business has to be sustainable). If something is too expensive in my personal use case, I will not buy or subscribe. The stock apps are very good and they are a fantastic starting point. I am also not an opponent of subscriptions per se. I am sad about the way Apple is handling developers and how they are pushing what they think is right. I believe in āfreeā markets and in the ability for customers to choose what they prefer. And that can be achieved even if there is only one App Store. I like the protection the App Store provides when it comes down to malware and security threats. Apart from that, Apple really should let the developers operate freely instead of getting them tangled up in rules and even more rules that apparently have become so chaotic that even Appleās reviewers do not seem to be able to keep up with them.
I do not know anything about Apple in China and, to be frank, I am just a tech enthusiast listening to podcasts and reading blogs. I would not consider myself as a person of too much knowledge in these matters.
