Would you mind elaborating? In particular, do you refer to the technical people ("no need to take care, even if I mess up no one will blame me") or the managers ("those cowards just want to avoid being accontable for their mistakes by blaming the process")? My last company had a culture of blameless post mortems, and also a strong culture of accountability, so definitely no one would fit the first definition. And the company was too small to have non technical managers. My current company (big corporation) officially supports blameless reaction to incidents, but internally has a strong culture of cover-up and blame ping-pong, but I still cannot think of anyone who would believe "blameless means no accountability". It just comes from deeply ingrained habits (lots of people do their whole career inside the company, lots of them even getting their masters at the company's own "university". Behavior is hard to change when everyone comes out of the same mould). I also think it comes from inadequate processes: where in the previous company the postmortem was mostly a meeting done by and for the technical team, my new company has a strong culture of "escalation meetings", where the highest managers quickly get drafted in, which obviously has a strong influence on the capacity to conduct an open and blameless process.
