This is true, but when safety is on the line it actually goes further than that. As an engineer you have an ethical duty to say no to making a product unsafe for end users or the general public.
It doesn’t matter if you get fired, if your boss goes to the media to bitch about you, if your boss threatens to sue you, you as an engineer hold a position of public trust to keep the people that use your product safe. If you don’t respect that and take it seriously, well we see where oceangate ended up.
