They don't care. Airbus is an EU project, meant to counterbalance Boeing and the US. The A380 was always a politically based development meant to project EU power by building the biggest jet. Airbus is to big to fail. The taxpayer will bail it out in the end if it all goes pearshaped.
As the GFC proved, "too big to fail" is a fallacy. And with the scarcity of money in the money go round that is the Eurozone, bailing out whole countries might prove more attractive than bailing out prestige projects. But, who knows? I don't think Airbus could fail merely on the unprofibility of that one design.
