The metadata that is _required_ to produce your monthly AWS bill reveals a ton of information about the success of your business and what is doing very well for you.
Doing analytics on customer billing is something that Amazon has every reason to be doing, and what Amazon does with that information can be anticompetitive or not.
There's definitely room for discussion over when what level of granularity is necessary and whether metadata at different levels of granularity should be shared with product vs. customer facing teams.
That didn't seem to be what the GP comment was about though - 'mining data from AWS servers' sounded to me like a much more invasive approach to client data.
There's a pretty obvious way to achieve this risk mitigation which is by spinning off AWS into a completely separate company with separate management accountable to a separate board with separately traded shares and not sharing any offices, employees or infrastructure with Amazon retail.
People who predicted the 2008 crash used to get tinfoil hats in the mail.
Why on earth would you think that? They did worse on their storefront, which has a much smaller migration burden than AWS, and while a few big brands made a stink and pulled out, it didn't even noticeably slow growth.
Doing this would blow a huge hole in that.
Do you really think banks are going to stay in AWS if this happens? Do you really think Salesforce is going to be OK with it? Do you think they'd ever do any US Govt business again?
Don't get me wrong, I wish you were right, I just don't think you are.
It's a conspiracy theory to believe that a company whose policy it is to not access data that is on their own platform, who was caught accessing said data, would violate such a policy?
If it were true that Amazon were taking sneaky peeks at data inside AWS related to retailers, and this became public, AWS as a business would be done.
The loud banging you'd be hearing would be the door closing as the last customer exited, followed by all the engineering staff who work on AWS as they see the writing on the wall.
Why would Amazon look to achieve some marginal advantage in its retail businesses at the risk of a total loss to one of its marquee businesses, AWS? It's an idiotic risk.
