You are right, data is private and confidential when it is ingested to the cloud and/or stored in the cloud, not when processed. Encryption of "data-in-use" is the 3rd leg in data protection of sensitive data, and it became possible with hw capabilities in new CPU chipsets, from AMD and Intel, as it has to be hardware based (better security and performance).

As storage and ingestion requires processing, that's the same as saying it's not private at any point when in the cloud.

And that's not necessarily a big deal. If you trust Google or AWS to hold all your business and customer data, no problem (and if your customers transitively have that trust). But I think there's a lot of denial about this fact: the cloud has all your data and all your customers data. Fixing that is really, really hard. It's not anywhere near as simple as Google are claiming in this announcement, certainly not "tick a box and it's switched on".
