No, I think 90% want to know if he really did something bad (Like, say Matt Lauer), or if he was fired over nothing, like complimenting a woman's appearance.
People do not get fired for that. If you think they do, then you haven’t been in the workplace for a long, long time.
If they brought in outside counsel to do the investigation, then it is pretty clear he did something either against the existing policies and probably outside the bounds of his contract.
And yes, I am sure FOX has zero tolerance for this stuff.
He should have known better.
