The article missed one huge factor: date farming by AWS/Amazon. If one has data on pricing and sales across retail and online channels on a national scale, how risky would a purchase of a retailer really be?

Do we know Amazon's policy on "peeking" into people's AWS data? I feel like they would have something against that in their ToS/Privacy Policy.
Multiple times I was trying to troubleshoot an issue and asked them to "just log into the database" and they said they have very strict policies against that.
There is no way they have any of Target's data.
