I suspect what he is saying is that people who probably had no visibility into the state of the Sony's security and certainly had no ability to influence it are unfortunate victims here. While security is difficult to measure and therefore difficult to manage and improve, it remains the responsibility of executives to allocate resources against that problem and it is they who ultimately bear the majority of the blame when the security posture falls short.
IMO the higher up the chain you are, the more responsibility you have to secure the systems you are responsible for.
I feel like it's a perceived lack of accountability (from the perspective of the hackers) of the executive team that leads to these kinds of leaks. When they feel they aren't seeing justice - as defined by them - then I think they're more motivated to do something about it themselves.
