I'm curious where you are getting that data from? The article says nothing about the data contained, and most other people in this thread either don't have access at all, or are stuck behind a 7 day wait time. Have you managed to get yours?

Also, what is your metric here? A lot of "journalists" comparing the takeouts from Facebook or Google use horrible metrics such as byte size, which make zero sense because these takeouts contain videos from Photos and files you've uploaded to Drive. It's in no way an indicator of how much "data" these companies collect.

Many people have commented on this, and the response I typically see (and which makes sense to me) is that Apple makes so much money from their products that they don't need to collect and monetize detailed user data (unlike Facebook, Google, et al.) and can easily afford to come to the user's defense and protection in that realm.
