I am a third party. I can load a non-Apple approved app onto an iOS device for free. Even ignoring jailbreaking by using Xcode. The app will only work for 7 days before I have to resign it but it doesn't need to be submitted or approved by Apple or follow their store guidelines at all. Altstore basically wraps that process up into a little bow to make it easier. Don't even need your own Mac.
I could also use Pythonista to write a working Apple I emulator. Is the iPhone still not general purpose PC?

I’d like to see the Apple 1 emulator please. I’d like to know which of iOS’ permissions you hit first.
You don't need any permission's because it's possible to build entirely within the sandbox of Pythonista!
I’d rather they all prioritize security, rather than extensibility.
Reading more about Pythonista, it’s seems unlikely that you could build a stateful Apple 1 emulator. But even so it looks cool. Arguably a little too permissive for my liking on iOS. I hope Apple closes all of those Inter-App communication channels. That seems like a security risk waiting to happen.
