It is possible that one of the difficulties for Boeing is that the tiniest anomaly in a system will result in no departure or an early return. Wheres on other new a/c they might take the tiny concern with them - no one is going to do that with the 787. This will make the stats look worse and be more public (above).
Boeing have only themselves to blame. If you rush the development and testing, you will have plenty of time to consider the problems during service - or not service - as the case may be.
