To me a unaccounted edge case in a tripple redundant system that can be fixed by an update forever feels different than Boeing routinely missing screws and not documenting them. Don't get me wrong, both things should never happen, but the first can even happen to very good teams with stellar safety and testing culture, while the latter is indicative of a broad problem. Missing an edge case nobody knew existed is not the same as not doing a very obvious thing that you should be able to do.
