> As much as it pains social justice warriors today, in English, the words 'he', 'his', and 'him' have a gender neutral usage.

'He' is sometimes used in this fashion, but it is an uncommon use, and it's arguable that in some contexts the author actually means a man and has not considered the possibility of a woman. Certainly in this case, why would you assume that it is used in a gender-neutral sense?

> And in any case, saying that a computer science security researcher is male is way less than a bit of entropy.

Fair point.
