no company can ultimately suceed if it does not have products the market will noy buy. If Eurocopter had an efficient spares such there were not hangars all over the world with AOG Eurocopters there machines would get used more and they would ultimately win when choices were being made as to which manufacturer to buy and then sell more spares. The cost of non perishable spares is minimal compared to the huge staff employed writing each other memo's and dealing with the same subject for the same client.
Airbus part of the same company understands that too well that if it is not as good as Boeing it does not get chosen again-and they are good.
Eurocopter just get the second rate team.
