For example, I don't imply, but often remind folks on Pprune that Airbus marketing has a European government-funded unfair advantage, versus what Boeing is allowed.
Lets not forget the cross-subsidisation through technology transfer from the military division that Boeing enjoys. Or the conveniently uncontested US military leasing of 100 767 tankers. Or the extreme political pressure placed on the government of Taiwan to buy Boeing instead of Airbus. Or Israel for that matter. Why did Emirates suddenly switch from Rolls Royce to an American engine manufacture after a high powered political lobby visited the UAE? Why did the WTO rule that export tax breaks for Boeing represented an illegal state subsidy?
