Companies don't have agency or feelings. If company leaders expect people to do their jobs properly only because they are getting paid, it's already an institutional failure, because it's not taking into account that individuals are fallible.
If the company does not have an established process to protect itself from human error, whether accidental or intentional (like an disgruntled employee going rogue), when shit hits the fan all its leaders can do is to find blame in the individual. But instead of blaming people and hoping that we can force everyone to avoid mistakes, a better alternative would be to design a system that can withstand human nature and fix the institutional process so that that error doesn't happen again. The problem is that to do this takes time and most company CEOs can not see much beyond the next fiscal year.
