HN is a very pro-Amazon place. Regardless of what Amazon does, at least one of the top 3 comments is always justifying Amazon's actions.
1. Scale is hard and downtime is hard, HNers either recognize the struggle or appreciate their lack of experience. When AWS fails many armchair architects come out to suggest solutions but many more techies just sympathize with the Amazonians.
2. Technically, Amazon has built something impressive. It might not be what you want, or what others have, but AWS is impressive in scale and scope and even reliability. Many people share credit where due.
3. One can criticize the treatment of warehouse and delivery workers that Amazon is known for, but this has little baring on the tech workers there nor AWS generally. So AWS stories tend to be free from the social critique the company as a whole receives.
