As to the problems with Boeing in particular, they mostly look like cost-cutting and short-termism; the 737 MAX, for instance, is transparently an attempt to squeeze a few more years out of an ancient no-longer-fit-for-purpose design. And the decisions that lead to that were probably made more like _20_ years ago; Boeing should have started developing the 737 replacement quite a while ago. This would suggest that Boeing has poor leadership.
(You could also argue that some of it's the unfortunate reality of the markets; the markets _might_ punish Boeing for making necessary investments with very long pay-off times.)
There is undoubtedly something fishy going on at Boeing, but that doesn’t mean that more commonplace accidents aren’t being comparatively overpublicised, or that they aren’t getting more traction than usual because there are now far more people waiting with baited breath to jump on anything that portrays Boeing negatively.
All I’m really saying that Boeing hate is now undoubtedly trendy, and that communities like HN are filled with people that have bought into the software engineer God complex enough to think that they can just intuitively understand something as complex as aviation. I’d barely consider myself anything more than a layperson but these Boeing incident threads are increasingly filled with people spouting BS. Again, there is certainly something going wrong at Boeing, but we are well into the territory where there’s a real need to separate signal from noise.
