If Epic wins I would gladly pay Apple for access to the app store. Apple’s review process and the standards they implement provide a lot of value to me. My fear if Epic wins is the iPhone app store becoming like the Mac app store: mostly empty. Because if there’s a way to escape compliance with Apple’s standards and still distribute your app then many developers will take the easy road.
You reply hints at these <issues> when you allow developers to distribute their software but doesn't give any specifics. What is your specific issue with how app distribution works on macOS? Are you running into low quality software that you purchased that's full of malware?
I enjoy the freedom of going to a repository and building or download a binary without having to use Apple's centralized system. I like paying the developer directly if you want. I've done it with 1Password and other applications. They're high quality software.
So you are saying that App store provides so little value to developers that nobody will want to use it unless they are forced to do so? Maybe once Apple faces competition, they will have to improve their store and attract developers by offering a better experience?
