I was an FB infra engineer in 2010. It's not accurate, there was already a "retro" SEV analysis process with a formal meeting run by Mike Schroepfer, who was then Director of Engineering. I attended many of them. He is a genuinely kind person who wouldn't have said anything so passive-aggressive. Also, many engineers broke the site at one time or another. I agree this is just a mutation of the Watson quote.
The only time I ever saw an engineer get roasted in the meeting was when they broke the site via some poor engineering (it happens), acknowledged the problem (great), promised to fix it, then the site went down two weeks later for the same reason (not great but it happens) and they tried to weasel out of responsibility by lying. Unfortunately for them there were a bunch of smart people in the room who saw right through it.
