I'm not sure why this is considered a sad thing. Minus the costs involved in shutting down production, they're all sunk costs. With this move, Airbus can utilize those resources for something else more lucrative and the company and its shareholders will be better off for it.
Unfortunately, it can all get very messy from here - and may well do so:
1) Google "Seattle Times" + "Boeing".
2) read the piece from 15th Feb. by Dominic Gates.
3) then absorb the history and analysis of the use/misuse of "RLI" and the likely content of the final WTO judgement due this year on the AB vs BA case.
4) note the previous highly-critical comments about the WTO already uttered by the President of the USA elsewhere.
5) then recall that there is a Trade War against China currently under way initiated by that same President. The grounds for the action is on the basis of China;s perceived violation of WTO trading and IP rules, among other damaging activities.
6) and now read the Gates piece again.
I think it is perfectly possible that this all has the potential to get very nasty between USA and the European countries who so readily accommodated AB's many requests for capital.
I really wish that AB had just paid the RLI back and so put a final stop to it all.
cheers (I hope).
