Citation needed, for sure. I certainly believe that most companies don't particularly value honesty, especially when pointing out managerial flaws. But looking at what she wrote with a manager's eyes, I don't see anything I'd fire her for. But like aylmao writes, I see it more as an impassioned and probably valid critique of DEI work that is more posture than substance. What I see is somebody who really cares about the problem, and who could be channeled into productive work as long as that work truly has impact.

I also suspect that if she'd written the equivalently passionate comment about a technical failure or bad product choices, people here would be cheering her on. Especially if she were a he.
