As you can see, they hired an outside legal firm to declare that they did nothing wrong in enabling said sexual harassment because there wasn’t a paper trail, despite them admitting that the victim was told to talk it out with the abuser.
You are assuming intent, and ignoring the false statements made. What I see is them hiring a third party to do an investigation, exactly what the public called for. Would you rather the former employee pay for it?
They followed up by threatening the victim with a lawsuit for continuing to speak out.
There was no threat, only a statement of fact that the evidence was strong enough for a defamation case, and that they did not wish do go down that path.
