You need an Apple developer account to even make software for iOS. Alternate app stores are distributed on the web, not Apple’s App Store. Since an alternative app store is an iOS app, Apple banning Epic’s developer account means they’re banned from making one.

Third party browser & JavaScript engine + ability to install web apps on the Home screen = third party app store that doesn’t have to pay Apple’s fees.

When Apple could force everyone to use Apple’s WebKit, web apps didn’t matter as much as Apple could limit WebKit features to push people to the App Store. E.g. it took ages to get push notifications on WebKit. If Google and Mozilla are free to make whatever improvements to their browser engines, the need to have native apps on the phone decreases considerably.

Next step: there’s a good argument to be made that the United States is not a nation. tldr: a nation is a group of people sharing ethnicity, language, culture. The United States is a country united by an idea, not an ethnicity.

It’s cheaper. In Japan manga volumes are about 700 yen, which is about $5 currently. No budget for color printing there. Manga is often drawn by one person who is already massively overworked just to hit serialization deadlines, so no time (nor budget for assistants) for coloring.
