Obviously experiences vary greatly, but I was on one of the largest AWS orgs and they were quite punitive. People would demand them for perceived slights, then assign reviewers that were tough or on their side. Many of my friends had different experiences, though.

Some orgs also use them to extract concessions from dependencies further up the chain. Upstream service won't fix an issue that's been causing problems for us? "unintentionally" let it become a SEV, so that we can send the CoE up the chain and get Jassy to drop the hammer on that team...

Hmm. I'm curious about which org that was.

I spent the slight majority of my time at AWS in RDS.
