Considering most CEOs are male by far, I'm sure there are dozens of cases historically where it's happened. This isn't the first time a company has been failing and they fire the CEO and hire someone else, only to fail in the end anyways.
Well, I didn't down vote you because I didn't think it was a terrible question. I am not well versed in business CEO history though, so I can't point out specific examples. I just was saying that given the thousands and thousands of businesses that have existed in history, this situation isn't unique.
I also am not sure how you'd distinguish she was getting criticized due to her gender as opposed to it just being an extremely iconic company from internet history that has steadily gone down the tubes. It's a bad situation and tons of people have lost their jobs, I'm not sure how one could speculate accurately that the criticisms are because she's female vs. the other dozens of issues.
If you could find an example of a guy in a similar situation who has received a similar level of criticism, then I think you could at least conclude that gender wasn't the primary factor in motivating criticism.
If you couldn't find an example, then not much could be concluded.
Last decade? In tech? That's more of a head scratcher...
Scully and then Amelio @ Apple? Fiorina @ HP, certainly after Eckhard Pfeiffer screwed the pooch at Compaq. C. Edward Acker after Sewell screwed up at Pan Am. Kay Whitmore at Kodak.
Edison was a horrible CEO; but of the many companies he founded, the only one that survives is the one that fired him early on. No one every hired him to be a turn-around person.
Turn arounds are hard. The company falters. New person brought in. That person fumbles. Yet another new person. Company recovers. If the company doesn't recover - you probably haven't heard of them.
