It's interesting that you're quoting that line as "the heart" of the piece, when it's the one line that seemed to reveal a less-than-reasonable motive: most of the rest of the editorial was about the way Taylor was fired, but this line was complaining that she was fired at all.

As an outsider to this drama, it sure sounds like people are angry mainly because this person was fired, and they liked her. They're clinging to the details of the way she was fired to give some weight to that indignation.
