I'm not upset at you for posting this, but I hate these type of articles. Ninety percent of the article is people roasting her, followed by a tweet contradicting it at the end.
It could all very well be true, and I have insight on this at all, but I'd wager that nearly every single work environment has co-workers that love to chime in about someone after the fact. If there's a history of poor performance, work ethic, abuse of power, etc, it's warranted, but some people just like their opinions to be heard. Personally, I've had really good managers and co-workers get trashed at my office after they left. It just happened yesterday, as a matter of fact. Mob mentality favors the negative.
sorry for the rant.
