> But how trustworthy are Google Drive logs, a record that only exists within Google, when what they've recorded helps their case?
Routinely-kept business records are common evidence in cases, and, while any evidence is subject to impeachment, "it supports the case of the party keeping the records" is almost never sufficient to get a trier of fact (jury in the case of a jury trial) to dismiss the evidence; you generally need either some more concrete evidence of fabrication or independent evidence contradicting the conclusion the evidence is offered to support.
Google Drive logs are fundamentally no different than email, or even paper business records, in this context.
