It seems that you missed their point: the toxicity is non-gendered. (I say you missed their point but they also kinda did a poor job of making it, FWIW.) There might be a point that Google's culture in practice is male-dominant but I think it's mistaken thinking that puts the toxicity on the male-dominance.

Consider your words as if they were being said about a woman:

> Proving you're smart by solving hard problems is a gorilla-chest-thumping exercise.

Isn't it still true?
