You definitely missed the part where Boeing offered a subsidy. We don't know the details of it but I am sure Boeing is doing something really costly to rival Airbus.
It is a temporary and immediate solution that will in many ways be subsidized. Qantas would be naive to not give it a look. I am sure Boeing will do almost anything to keep Qantas from going to Airbus.
I think you need to the blame falls on the government for removing the funding that required them to switch to a system that did not provide direct oversight of the certification process.
Blaming Boeing (justified) but neglecting to also blame the agency in charge of oversight is in fact ignoring the big picture. If you add the FAA to the equation then you have to remember those who are in charge of funding them.
