>But blame firing/piping more engineers for an incident should NOT be on the table.

There has to be a level of fuck up where a resignation is appropriate, maybe this doesn't meet your bar, but surely you recognize that there exists a limit of incompetence that proves that one is not up to the demands for the job.

I used to be on your camp, blameless postmortems, the truth is more important than assigning blame and in all likelihood it's a systemic problem. But with time I realized two things, 1 there's actually incompetent people, 2 if you wrongly get blamed and you don't blame someone else, then it's your head that rolls, hate the game not the player, you have to assign blame to someone else if you are accused.
