Obviously, there are still details to be learned before we pass final judgement on this incident.
Some of you are suggesting that there needs to better technology to prevent mishandling of a fuel leak on what is already a high technology aircraft. Others think the A330 fuel management system is overly complicated, an opinion which is completely without factual basis. The A330 and its' relatives have a very simple little feature which can be quite helpful in this regard. It is called EFOB (estimated fuel on board) at destination. It seems to me that keeping an eye on this figure, combined with consistent fuel checks over waypoints, should yield clues to fuel leaks rather simply. Why complicate things further?
