Free Scenario: I install a photo sharing app. I use it to only post photos that I take while going on hikes or of my food. Those are always in an Album called "foodpics" or similar, and every time I open their app, I select the "foodpics" folder, then the image inside of it and then go through the app's upload flow. Why should the photo app get access to the rest of my library of photos, like the ones in "business receipts" or "my son" that I would never upload to said photo sharing site? Sometimes you want to use the app, but you don't want it to have a world-view of your phone. In a perfect world the photo sharing app should only get access to the individual photos that I choose to share with it (either through the Photos app or an OS-level file selector)
