Amazon did not destroy diapers.com.

Diapers.com aka Quidsi was already operating at a loss when it was acquired by Amazon. It's whole business model was using VC-funding to offer products below sustainable costs with the goal of eventually jacking up prices once they drove out smaller/local competitors. Amazon used its own business model against it by dropping prices even lower, knowing that the VC investors couldn't afford it.

Walmart passed on buying Quidsi when Walmart was thinking about launching its own e-commerce platform because the business model was unsustainable. Walmart decided they would rather spend several hundred millions building out their own platform then to buy an existing website with millions of customers.
