Workable != competitive, and in an industry as cutthroat in aviation airlines want the absolute best in fuel efficiency and reliability to undercut their competitors by $5.
There are other commercial aircraft manufacturers but essentially in each size segment you will only see two players. Embraer doesn‘t make any direct competitors with Airbus or Boeing, as an example.
Embraer jets got rebranded as A220s not that long ago, great planes that took over the market that served by short 737s and A319/18s. No competition for the bigger planes, that is true.
Them selling out to Airbus had more to do with general issues at the parent conglomerate (they also exited trains and snowmobiles to raise cash). But they still make corporate jets.
Ha, I always mix up Bombardier, Embraer, Boeing and Airbus when it comes to whom bought whom. And yes, Bombardier always made great aircraft. Embraer as well, by the way.
