That "CYA" response really doesn't feel like "us" to me, at least not the AWS side. I can't speak to the experiences on the store side, nor on the devices side. Over in AWS, we practice the "blameless postmortem" model you'll read about from time to time, and it is very rare to see any professional or personal consequences beyond some light joking come about from "breaking prod"

To that point, I know personally the engineers who triggered several of the AWS outages you will have read about in the news over the last decade and more. Some of them are still with us, some have been promoted since then.
