If you have any evidence that Amazon is accessing the data of their leased tenants, that would be an earth shattering indictment of the entire cloud industry

It would be akin to accusing Datapipe or any other provider of pulling drives out of any client with racked servers in their data centers.

And that’s exactly why high security applications don’t use cloud like this; because that can never be guaranteed by some policy compliance certificate. That’s the only thing stopping them from pulling drives, etc.
