Wow, I'm surprised to see the comments here being hateful towards this statement. I don't think it's contradictory at all. The stance he takes is that any subject is up for debate, so long as you don't step out of line with respect to the code of conduct. The guy who was fired was way out of line, far beyond any reasonable limits to topics of discussion. Even as a particularly opinionated person myself, who would be…
What did the author say that was "out of line"? Can you please cite a section of the essay and explain?
Note: Please see this response to the memo from four scientists who study the field of psychology: http://archive.is/z6xxP
The reason given by Google for the author's termination was "advancing harmful gender stereotypes". I didn't see any evidence in the memo of "advancing harmful gender stereotypes". Where are the stereotypes? Where's the evidence that they're harmful? Is the author really advancing them? The author appears to be referencing scientific research into the topics that he mentioned. Scientific research into sex differences is not "harmful stereotypes".
The way in which the Google CEO's reply is worded gives me the impression that they don't even understand that the author's claims are scientific ones. For example:
> Our co-workers shouldn’t have to worry that each time they open their mouths to speak in a meeting, they have to prove that they are not like the memo states, being “agreeable” rather than “assertive,” showing a “lower stress tolerance,” or being “neurotic.”
These terms -- agreeableness, neurotic -- are personality traits in the field of psychology. There is a significant amount of research into how men and women differ in these traits. See Wikipedia for sources: https://en.wikipedia.org/wiki/Neuroticism#Sex_differences
> This paper investigates gender differences in personality traits, both at the level of the Big Five and at the sublevel of two aspects within each Big Five domain. Replicating previous findings, women reported higher Big Five Extraversion, Agreeableness, and Neuroticism scores than men.

The author's mention of terms like "neuroticism" and "agreeableness" are statements of personality trait trends established by scientific research, not personal views or stereotypes. The message from Google's CEO seems to interpret them as personal insults, thereby missing the point of the essay.
The original memo raises points like: women tend to have higher neuroticism on average (low stress tolerance) than men. If some tech jobs have high stress, then is it possible fewer women than men seek those jobs? That seems like a reasonable question to explore, to me, and a question that's grounded in existing scientific research, not the promulgation of a stereotype.
The author also cited other research such as "Women, careers, and work-life preferences": https://is.muni.cz/el/1423/jaro2011/SPP457/um/23632422/Hakim...
