The thing Googlers and Xooglers alike seem absolutely unable to grapple with is that Google itself is a major privacy threat, and we don't want Google itself to have this information.
The fox is guarding the henhouse, and all the fox is doing is telling us it's protecting it from other foxes.
The article here talks about how google executives deliberately made privacy settings harder to find because the people were actually using them. The article also suggests, through court documents, that google coerced other manufacturers to do the same.
This is almost impossible by design. As mentioned before, every field on a protobuf is tagged for sensitivity, meaning right down to the bare disks there is privacy controls on data.
Engineers under orders to decrypt & copy data literally could not, without a delegated authority from senior people (some will be GDPR officers too), and there would need to be a staggering level of process failure just to get at the data for a few users.
Ultimately you have to decide if you trust Larry & Sergey, nobody else could make this happen. But insider risk just isn't going to happen from a company that treats user data like military treat classified documents.
