What I think is missing from this article is a description of why an app dev would need access to the user's environment. Without this link, it all seems a bit paranoid, since Apple could just cut off developers from knowing anything about the background on which the app is being displayed. However, I believe a WSJ writeup described a FPS in which the furniture in your room become barriers behind which you can hide. If that's the case, then it seems like this is a very real issue, and you should treat interactive apps like this as if you are uploading an image of your entire room to the app dev, for them to use/monetize however they see fit.
