My point (poorly made) is that there is a difference between blame and responsibility. "Blame" is answering the question "who screwed up"; "responsibility" is answering the question "who is going to make this better". The original tweet-stream post was making the argument that the software (and so naturally the software people) did nothing wrong and thus was not to blame, but also made the argument that since everything else was wrong ("not my fault!") that there was nothing the software people could have done to make it better, i.e., they have no responsibility.
