They largely badmouth people. I have seen very harsh things written after the employee was fired, with the employee having no opportunity to answer. Harsher for ICs than for Director and up – cowardice is always cheap.

You cannot write that that person is not at the level of their peers, that she was not able to communicate with the stakeholders in a company-wide email, with no opportunity for the fired person to comment.

In my book, that is all very unfair. I hope you are not used to that behavior, either actively or passively.
