I've never put it on the cloud, but I've had legal cases I worked on that would have definitely flagged automated review triggers. Its shocking to me that there's such a difference in what companies do with your data if you upload it to Google Drive vs. iCloud Drive these days.
Anecdotally, the owner of the SV Seeker Youtube channel had their Youtube account terminated and lost all of their videos because they had uploaded some...adult content for a single viewer as a private video, which Youtube scanned and detected. "Private" just means "not discoverable."
TLDR Don't use Google storage in any capacity as a source of truth or sole copy, and encrypt if you don't want the data scanned, inspected, etc.

Lawsuit data has been sent to me more than once via Google Drive share links -- makes me think I'm not the only one who is unaware of the scanning practices.
