Yes, that sounds awfully suspicious and counterproductive. It sounds like they actually want to silence any reference to wrongdoing, as if potential whistleblowers and offenders must be held accountable to deeply contrasting morality bars.
To me, asking people who object to their employer's moral, ethical, and/or criminal violations to resign and go away has the same vibes as calling for people who criticism the government to exile: their goal is not to fix things, is to silence dissent.
