Bullshit.

I downloaded Facebook's data on me and found about 40 websites they said they had shared my profile with. I didn't authorize that. FB doesn't give me the ability to "revoke" permission to have my info shared with them, either. Nor does it allow me to request that the information on me given to those third parties be deleted.

Actually, you absolutely can on https://www.facebook.com/ads/preferences/

- Advertisers you've interacted with

- - Who have added their contact list to Facebook

Hover over those you don’t know about; the X let you “Remove” those, i.e. ask Facebook to exclude you from those advertisers’ targeting.

If you are in Europe, you should be able, starting next month, to leverage that list to ask those advertisers how they got your data, and expose data brokers. Facebook is simply (finally) offering you the ability to track data brokers.

Once the data has been given to a third party, we can no longer be guaranteed that the third party will delete it. That was one of the main problems with Cambridge Analytica -- they claimed to have deleted data but may not have actually done so.

Any company can upload a list of email addresses to facebook and say they have a relationship with you and then facebook will allow that company to market you. Its obviously against ToS to go out and purchase a list of emails and upload it to facebook and show those people ads. But uh, facebook can't prevent that without killing the feature. So in this case its not facebook sharing data, but companies lying to facebook and facebook going along with it to get paid.

FYI I've read that the "account download" doens't give you all the data. If you're outside the US & Canada, you can make a formal request

Which section was this in the downloaded archive? I'm not aware of any situations which this would happen except using "Log in with Facebook".
