I just happened across this report from 2019, in which Oracle outlines, for an Australian governmental entity, all the ways Google collects data and builds profiles on mostly unwitting users of digital services and devices.
Lifehacker website article: What You Need To Know About Your Google Shadow Profile
…which makes reference to Oracle’s submission to the Australian Competition and Consumer Commission (ACCC): (72-page PDF) https://www.accc.gov.au/system/files/Oracle%20Corporation%20(March%202019).PDF
[EDIT: 17-page appendix/summary from above report, i.e. the interesting bits: https://assets.publishing.service.gov.uk/media/5e1c4985e5274a06b7450a13/Oracle_-_Response_to_SoS_-_Appendix_4_-_Google_Shadow_Profiles.pdf ]
None of this is surprising, of course, but it’s “interesting” to see how Google markets its advertising (surveillance) powers to its customers.
(Not that Oracle wouldn’t like a big slice of that ad pie, too.)
