Was Jill Abramson fired because she questioned the gender pay gap at The New York Times?

Several weeks ago, I'm told, Abramson discovered that her pay and her pension benefits as both executive editor and, before that, as managing editor, were considerably less than the pay and pension benefits of Bill Keller, the male editor whom she replaced in both jobs. "She confronted the top brass," one close associate said, and this may have fed into the management's narrative that she was "pushy," a characterization that, for many, has an inescapably gendered aspect.... Whether Abramson was right or wrong, both sides were left unhappy. [The New Yorker]
