Remember Boeing weaponizing the US government to block the Bombardier C Series, claiming that they were an "unfair competitor" even though Boeing weren't even offering a plane in the same category? Even though Bombardier offered them a huge piece of the pie and they refused? They blatantly did it because they thought it was going to bankrupt Bombardier, and it almost succeeded.
Canada remembers. Fuck you Boeing and fuck the corrupt American politicians who keep making a mockery of trade regulations at their request.
