I don't think anyone is pretending that the cabin issues are the silver bullet. What is depressing for me is that we have been here before with the Cormorant crash and before that the Scillies Isles - both crashes where escape was severely compromised - although for differing reasons.
Recently offshore I was on the receiving end of some company propaganda for the 're-introduction of the 332L2'. In that it stated that flying at night was no more dangerous than during the day. With that sort of near complete denial of the facts, I cannot see the helicopter operators as potential leaders in improving the situation.
They should be, much of the discussion here demonstrates a knowledge of how in many cases to fix things, or certainly improve them, so the expertise exists. It just appears that the safety culture to support those approaches is pretty tenuous.
