But it doesn’t mean she’s right, it just means she feels strongly about it.
In general, whistleblowers should be attended to, due consideration should be given to what they are risking.
But if you're going to do it, you need to build up a case and make it carefully and dispassionately, and above all maintain your professionalism. This reads more like a divorce proceeding.
Last time I checked, the whistleblower wasn't raving or cursing on the way out.
It sounds like you're just generally uncomfortable with questioning authority.
In this case, it sounds like they told her to make a change, she said she disagreed but made the change anyway. And then they fired her? For what? This just doesn't ring true.
The coverup idea doesn't make much sense either. Apparently the "deleted" data was minor detail that would be published in a day or two anyway. Is it even material? Would anyone even be looking at it, aside from this scandal? Also sounds off.
My guess is that (right or wrong), she was already on someone's shitlist, and this was the last straw. The "my successors will be liars" thing certainly wouldn't make me want to work with her.
There will be an investigation, as there should be. I suspect there's little or no fire.
For some reason, this statement strikes me as being cruel to someone who is willing to take a stand on moral principles. For someone to buck the orders, it takes a lot of courage and be able to stand up under pressure. There are no textbook examples of how to whistleblow and I think we owe these people who are willing to call out problems as they see it a more charitable hearing.
