It doesn't really help Airbus. Their production lines are sold out for ~7 years. They expect to increase production over time, but there is a long complex supply chain, so it is a slow steady uptick, not a rapid change. (Rapid changes are also how you stress suppliers financially and cause quality issues.) Then engines on some Airbus planes are having supply problems too, and existing engines are requiring more maintenance and earlier parts replacements than expected, leading to grounded aircraft.

It is very normal for airlines to mention the manufacturers, because that is how they do price negotiation.
