Games are the main appstore revenue driver, and I don't think that game ports have much to do with iOs standards. It isn't like Fortnite or Genshin Impact on iPhone is significantly different than on Android.
Genshin Impact is (potentially) an interesting case - the iOS version has supported game controllers for almost 3 years now, but there's been no hint of support coming for Android. There's definitely some suspicion in the Genshin community that Apple has an understanding or agreement with Hoyoverse to keep iOS the premier mobile platform.
Would it be legal under US law for Apple to make payments to Genshin to keep iOS as the premier mobile platform? Related: Similar question if Sony wanted to guarantee Final Fantasy was always better on their platforms.
True, but there is also a business opportunity for dramatically simplifying game deployment, not only web apps.
Unity has tools that can partially help with that but their execution also sucks. You still need some half-working script downloaded from Github or some random site to deploy to Apple/Google if you don't want the hassle of using the default tools.
It's the same for consoles. It's an ungodly pain in the ass even with Unity. Godot makes some of its money by porting to consoles, for example. But I don't know if there's any money there for a scalable solution.
It means video games. And even amongst the most predatory mobile games, not all of them use gambling-adjacent "gacha" mechanics, plenty just have mountains of microtransactions.
Apple cracked down on traditional gaming on iOS, and as an unforseen side effect, yes, "mobile gaming" means suggestive gambling apps that are eating the world.
