It might be a good demonstration of that if the engineers had spotted the safety problem. As far as anyone can tell, they didn't - the press took some internal e-mails worrying about other safety problems which turned out not to actually matter, spun them as proof that their employees knew that the 737 Max was unsafe, and confused people like the commented you're replying to into thinking the problem was actually spotted internally. To give some idea about how overblown this was, the really juicy-sounding email comments were about problems with the simulator, not the actual plane. The fact that Boeing had a culture where people could speak their mind and those comments were recorded left us all less informed.
