I have no idea what the code culture looks like at Boeing, but it's possible that if engineers had more skin in the game, the 737 MAX problem wouldn't have happened. When you depend on a QA team, it's easy to throw code that compiles over the fence and say it's someone else's problem, now.
The 737max problem had nothing to do with software bugs. The software worked exactly as specified, it's the higher-level system design which was wrong.
