Sometimes I wonder what the chances are that certain (highly privileged) staff at Google (or other similar data storage or e-mail companies) could run a query across Google Drive looking for a specific public key. Much like a malware scanner, just looking for "a key", just to see if there is an account matching. Unofficially, of course. A rogue employee perhaps. And, what if, in such a case, the employee (in the best of cases) reports the person anonymously, or in other cases, takes off with the private key if also found.
Or does anyone know if the data is so encrypted that nobody at Google can override? I would highly doubt that, looking at US law enforcement pressure. And I am sure there's a million and one barriers and access requests blocking raw queries, but technically...
Of course, a hefty hefty conspiracy-laden thought, but I just found myself curious if that would even remotely be an option.
