It's my fault that I wasn't clear in my request: I was specifically requesting some fundamentally new privacy-centric research paper, not pre-existing technologies like SELinux or x.509 being added as a check-list item to appease enterprise customers.

I.e.: From what I can tell, Google spends approximately $0 on privacy research such as security technology that only benefits end-users.

You linked to a bunch of security technologies that Google just copy-pasted into their products to compete with Apple and Microsoft, or to meet large customer requirements.

Also note that GCP is one of the few offerings Google has where the "users are the customers" instead of products. Despite this, there's nothing in that whitepaper you linked that impresses me as unique or special about GCP in comparison to AWS or Azure. I never hear anything out of Google that's even vaguely privacy-first, even in such divisions.

Linking to a paper with the word "privacy" in it from Facebook is just hilarious.
