No. Amazon's culture is super big on blaming the system. I know of incidents where operators made mistakes doing stuff that directly caused really big outages - the postmortems were entirely about the (lack of) safety of the tooling involved that allowed a single person to make such a mistake, and involved examining all the tooling of entire business units to try to identify other tools that could have such an impact. No individual blaming is involved - and in fact, postmortems always refer to "the engineer" or "the operator" and never include names.
