You mixed up a lot of things here. On practical side: execs, and accounting already legally must do paperwork, however shareholders want them to go well beyond that. And you can't force people to do job properly just by legally obliging them, otherwise Soviet Union would not fail.
On moral side: business in general (and startups especially) requires navigation between things many of which are unpredictable, and plenty are beyond your control. Also I've seen startups failing because of software bugs, and technical limitations. In this particular case, do you know about any obvious wrongdoing? If not you probably shouldn't auto-assigning blame on "them".
