All smartphones are a privacy/security shit show, Apple is no exception.
Today the walls in the hated ‘walled garden’ are not high enough.
The reality: these exceptions are made in a way that is exposed to external users which is much more transparent than most companies would be. It is stupid that Uber still has access if they don’t need it anymore. If you have to do a demo and it has to work before it is ready you have to make tough decisions.
Sneaking around like this only begs the question: what else aren't they telling you?
Even if your architecture is so hosed that you are screencap'ing the actual screen to get an image to ship over a network connection … multiple people thought that tradeoff with security was worth it?
No, but you do need the ability to render in the background, and apps aren't allowed to do any GPU-based rendering in the background (you can't touch an OpenGL context, and while I haven't actually confirmed this I assume you can't touch a Metal one either). This entitlement probably let them skip that restriction to do fast rendering in the background.
