On Android I’ve seen even Google apps ask for camera permissions, I’m making a choice about whether I want this specific app to have access to my camera, whether it comes from Apple or any other developer doesn’t matter. I should be able to disable the camera access for any app including the built-in camera app.
I think what many of us want and expect is a bullet proof permission system for the app store that doesn't contain surprises, gotchas, and magic entitlements that are ripe for exploitation (see for example PsychicPaper)
