It's very often the case that the person at the pointy end gets blamed for failing to block the last hole in the Swiss cheese.
Sure, both pilot and instructor/check pilot should have fixed this, but if the rest of the system isn't good enough, then it should also take some of the heat.
Remember, proper accident investigations determine causes, they don't assign blame.
Even if a pilot makes a mistake, they may have been put into a position where a mistake was the most likely outcome.
I'm not saying that's the case here, but it might be so, and we may never know.
The tendency for some (in the media, or vested interests in the whole system of systems that may also be causal) to stop looking for causes when they can pin it on pilot error does the cause of flight safety no favours.
It's also disappointing that many think that the presencel of ovaries in the pilot is sufficient reason to stop looking for other contributors.
