They seem to be worried about apps that include libraries, and those libraries can read the screen that the app itself is presenting.
If I’ve understood this correctly, I think it’s a non-issue. App developers using 3rd-party code in their apps need to trust that code. If they don’t trust it, it could do anything. (In principle you could have another level of sandboxing between libraries and the main app code, but that’s not something that any OS I’ve ever seen does.)
iOS would be vulnerable to essentially the same issues.
