The overall conclusion, which I seem to recall Damore taking great pains to clarify, is that individual women who happen to be competitive, driven, and resilient to stress can and do thrive in the tech industry, while individual men who lack those traits can and do struggle, but the differing distribution of those traits across the entire population will affect population-level statistics even absent overt discrimination.

Rounding that off to "women are less suited to work in tech" is completely dishonest, because there was never any claim that each and every woman is less suited for the tech industry than a man. A more accurate summary would be, "fewer women are suited to work in tech".
