It did that.

It did this too. But I'd argue the NYT opinion piece is too vague here. "made statements about" does really mean anything. I suppose the "suitability for" is a bit wrong. More like "biological inclination towards" technical jobs?
That changes things slightly but I can't see it as a huge misrepresentation.
The underlying idea of the memo is that biology can partly explain women's career choices (true) and that Google should recognize this and factor it into their diversity targets more than they do. That second part is highly debatable. Without controlling for gender bias and many cultural/historical effects, I'm doubtful we can even really begin to detect how much biology influences the choices of any given individual in the real world. How can we blame biology for a woman's choice if the mere fact that she's a woman causes her to be reviewed more harshly by others for the same work? Taken less seriously? Etc etc. These are real effects, and until they are gone, it will be impossible to determine what role biology plays on average participation levels in tech.
