Apparently, the WTO say that Boeing are at least as bad as EADS on the subsidy front. So that argument pretty much washes both ways.
This is a bizarrely complicated story and it does seem to depend on what report of the report you read or who you ask. The WTO reports are contradictory, obfuscated and puzzling to say the least, and I think that is the way they like it. But as far as I can ascertain, it seems that Airbus has never made money.
There is certainly some interesting stuff about how Airbus financed their development and sales in the book "How Boeing Defied the Airbus Challenge" by Moham Pandey. Obviously a biased account coming from a Boeing guy and how true the picture is paint, I cannot tell; but it seems consistent with how the EU manages its affairs!
