Earlier quoted context omitted.
Info about what products sell well? Amazon has a thriving white label business and they can use it to decide what to make.
And we think they need to risk the lost of business of breaking into your data on AWS to get this information? They somehow have no other way to infer this? How much business is this thriving Amazon-made products line? It's a fraction of AWS's profits considering retail's overall profits.
That's actually the point. So what if they're using "anonymous" or other indirect data? If "Amazon.com" might be benefiting from AWS data of any kind then it needs to be investigated as potentially anti-competitive.
