At it's most basic level it's all communications. No different than jailers reading the letters of prisoners except with a distinct difference; Memory.

>Researching further online, it seems that these concerns was raised as far back as 2015 by a StackOverflow user Patrick Peccattee who raised questions about the images uploaded on Facebook which contain the IPTC/IIM fields which are added automatically during the uploading process. It seems two tags were added named “Special Instructions” and “Original Transmission Reference”.
This was further elaborated by Edin Jusupovic, a cybersecurity expert with a twitter post back in July 2019 which states that this enables Facebook to track photos outside of their platform with high precision and to track who originally uploaded the photos.
The encodings are visible within the metadata however Jusupovic warned that “if the technology is weaponised then Facebook could potentially track its users without zero proof”.
