No, Facebook is not telling you everything
Found on Privacy International on Monday, 02 March 2020
Facebook announced the “Download Your Information” feature allowing users to download all the information that the company have on them since the creation of the account.
To put it simply, this tool is not what Facebook claims. The list of advertisers is incomplete and changes over time.
ack of information and difficulties in exercising rights, renforces an opaque environment where people are unaware of how their data is gathered, shared and used to profile and target them.
Of course Facebook does not want you to know how you get sold. There is absolutely zero interest to make it public; it should even be pretty safe to assume that Facebook works behind the scenes against legal requirements.
