Nope. Hurts overall experience. Not only the App's won't be curated the same as the other ones, but now I would have to maybe reach to some webside to download a .ipa file or to download a secondary App store to get a apps that otherwise would be available on App Store.
Then keep using the curated store? It only hurts if Apple's store can't compete with alternative ones. There's no such problem on Android because developers and users are fine with the Play Store.
Epic even tried doing a sideloaded Fortnite for Android and people didn't download it, so they came back.
As I said, they tried and failed because nobody downloaded it. I'm not sure why you're suddenly bringing Epic's motives into a comment chain about the desirability of sideloading though? Epic is obviously looking to skirt store fees and doesn't actually prefer to run their own store, but that has nothing to do with anything above in the chain.
