Embraer was a smaller manufacturer, much smaller than Boeing. The had some success, but it was tough for them to compete with Boeing, especially because Boeing bullied them through regulators. They outmanoeuvred Boeing by letting Airbus buy them for 1 dollar. Now Embraer planes are rebranded as Airbus 200 series
It's also not clear at all that that was a win for Bombardier, other than giving a free win to Airbus to spite Boeing. Given up the project that they were relying on for the future direction of the company for a nominal sum?
Airbus made out like bandits, and the government of Quebec cut their losses, but Bombardier almost certainly lost as badly as Boeing in the C-Series/A200 outcome.
