The engine that failed on the Southwest flight was a CFM International CFM56, which has also been used on multiple Airbus planes including the A320. The engine itself as well as the containment mechanism that’s supposed to prevent this kind of situation were the responsibility of CFM and had nothing to do with Boeing. This could just as easily have happened on an A320.

This example only serves to highlight how popular narratives take hold and get reinforced by laypeople.

Boeing absolutely deserves to be raked through the coals over MCAS, over their deteriorating engineering culture, and over regulatory capture. But blame them for the things they actually carry responsibility for.
