Envy
Boeing has nothing that can compete with Airbus A321 LR/ XLR, and in the light of the recent scandals regarding Boeings commercial aircraft division, it seems like pure envy from the beancounters at Boeing.
Boeing should focus on repairing their tarnished reputation,instead of trying to smear their competitors.
When it comes to the narrow isle airplane market, Boeing needs to develop a replacement for the antique B737. Max was one stretch too much for this 1960s design.
On top of that Boeing has until recently done everything to hide the quality problems with the B787.
Boeing used to be a proud manufacturer of quality aircraft, those days are unfortunately long gone.
