The data described in that article (Eg MAC Address) has virtually zero overlap with the kind of data GP mentioned (contact list, gallery). Most people only care about the latter.
btw "The researchers discovered that the Shutterfly app was accessing the location tags of photos' EXIF metadata. All that's required is the READ_EXTERNAL_STORAGE permission" sounds ridiculous. If you grant permission to read entire files, of course the app can read metadata.
