Missing from the list is any way to find out what some of these listed entities mean. For example, under "Advertisers who uploaded a contact list with your information" is claimed "Nebula Mars".

It both meaningless in its terminally symbolic state and deeply meaningful as an indicator of where my data is truly living in the world.
