It may come as a surprise, but I have used Amazon. Both on a professional and personal basis! (I say this tongue in cheek).

I know businesses that depend on Amazon.com as a primary sales channel were affected, but they don't pay Amazon to sell their product (maybe Pro merchants are the exception). I think they owe us Prime members an outage report even more on that basis.

In any case, I think it would be a good idea for them to write an incident report, but don't think it's comparable.

edit: I give. Like I said, I think it's different than AWS/GCP outages, but I think your point is great and I think it's a good idea they pubish a report on it. Look forward to seeing it someday.
