Instead, Sundar found it necessary to lie in his official statement about what Damore had said. He defamed him by saying that his memo contained things that are contrary to what the memo actually says and that Damore himself would certainly denounce if asked. Because, presumably, Sundar felt it was preferable to appease a mob by acquiescing in their villification of a Google employee.

That is what is this particular post claims makes Sundar a bad CEO. I don't know if that's true - that is, whether it makes him an ineffective CEO, whether his actions were good for Google in the long run; that remains to be seen. But the author of this piece feels that it was a morally wrong action (and I agree).
