FWIW, I work on homomorphic encryption at Google, and Google has all kinds of other (non-FHE) privacy enhancing tech, such as differential privacy, federated learning, and https://github.com/google/private-join-and-compute which are deployed at scale.

Perhaps it's not as visible because Google hasn't defaulted to opt-in for most of these? Or because a lot of it is B2B and Google-internal (e.g., a differential-privacy layer on top of SQL for internal metrics)

[edit]: this link was a very vague press release that doesn't say exactly how Google uses it: https://security.googleblog.com/2019/06/helping-organization...

uhhh yeah it's not visible because it's not used for anything. because it runs contrary to Google's entire raison d'être. if it's not turned on by default, what is even the point of doing it at all other than to pacify engineers who are perfectly happy to miss the forest for the trees? it's kind of like saying that you have the power of invisibility, but it only works if no one is looking at you.
