Especially since Boeing had already spent good money to get the Embraer plane in their lineup, and their actions "gave" its biggest competitor to Airbus for free. And in the other side of it, the deal will also majorly benefit Bombardier overall, obviously compared to no deal, but even long term compared with going on their own; Airbus is now pushing the plane hard like a normal part of their lineup, it doesn't compete with another Airbus plane since they didn't have one there yet (they were like Boeing except they snapped the Embraer one first). And the plane having access to the entire Airbus network is a big big plus (which is pretty much why it was instantly renamed A220, making it clear to customer it was a long term fully supported Airbus plane not a temporary off shot). Even the Québec gov is happy since the deal protects all the jobs and manufacturing locations, only difference is final assembly done in Alabama, and only for US customers. Also, Airbus was supposed to make their own and then compete directly with Bombardier too. Making two ennemies ally with each other is a really dumb move, and good luck taking it back once they both start reaping the benefits of that alliance.
