You say that, but consider that they might not have used the word “browser” because super apps are not the same (your attempted redefinition is not how that term is normally used). That's going back to the App Store control of code distribution, there's certainly no technical reason why someone can't use HTML5 or JavaScript in an iOS app given how many do that every day.

Again, I'm not saying that what Apple is doing is blameless but it's important to read the actual DOJ cases so you can understand why these aren't the same. For example, you baldly assert “That is pretty much what Apple is doing” completely missing that Apple is only controlling what you can do with their hardware and is making no effort to prevent, say, Google or Samsung from doing something different on their own hardware. That's significantly different from Microsoft preventing Dell, IBM, Gateway, etc. from shipping alternate operating systems and those kind of legal distinctions matter a lot in court.
