I read the discussion. They only want one little bit of access but it's all or nothing. There's no read-wallpaper permission. And while it's a choice made by Kindle it wasn't locked out at the time it was made, thus it can't be for the purpose of locking it out. They put their data under their own directory and now that space is restricted. The Windows file system can see it but apps can't see anything but their own. Mostly, a good idea, but it's locked even to apps whose reason for existence is accessing various files.
