I dont see how expecting better designs and models from Boeing is a bad thing.
Airbus made a similar gamble with the A380 - which arrived about 15 years too late. Boeing had already gotten a stranglehold on the large jet segment with the more efficient twin-engine 777 and will probably keep that lead for some time to come, killing off both the A380 and their own 747-8 in the process. The medium-large segment continues to be competitive, with the 787 and A350 both selling well.
But Boeing has won the large jet market just when it appears most the future profit growth is going to come from the smaller jet market. The MAX's problems make it look like - suddenly - Boeing does not have a solid entry in that race.
