There's "blame" and there's "fault". Faults are correctable, blame tries to place responsibility on actors. Few faults can be corrected without acknowledging where responsibility lies. There are multiple kinds of responsibility however. Responsibility for the cause and responsibility for fixing it. The same party who caused the issue isn't necessarily qualified (or authorized) to address it. The idea behind blameless postmortems is to be descriptive without calling out bad action, and evaluating the fault holistically, and acknowledging the reason most faults occur is a failure of processes not necessarily a failure of a person. Fixing processes is much more scalable.
