I don't understand why the man at Google got fired for saying male and female brain structures are inherently different...

People don't care about surveillance and will never revolt over it. Google aped the Feminist and Diversity mindset to become 'woke' in the eyes of the politically active mongs on social media so they divided any opposition.

I don't understand why Google is still allowed to exist

The petty bourgeoisie used to care about it when the Soviet Union was allegedly doing it.

What obstacles? I honestly don't know why corporate America went full diversity and egalitarianism. I know many Marxists claim it is an attempt to uniformly commodify human beings as labor. The immediate objection I see to this is that if the central claim that groups of people, like the sexes, are on average differently capable of different activities, and if the other claim is true that corporations actually raise people up despite their proficiency at certain tasks, then how is this good for capital? Sure, a wider pool of about equal labor is good for capital, but in a zero-sum game of hiring a certain amount of workers with a certain amount of money for wages, why hire some less skilled women because of "diversity"?

But profits are the overwhelming driver of their decisions. If I were to guess I'd say that this is all a sort of delirious (at this point) child of the neoliberal tactics to destroy the left since the cold war. Diversity is a defense mechanism, a reframing of the conversation which diverts attention away from worker-owner conflicts, and though it may hurt company profits a little bit to put less qualified people into certain roles it also theoretically helps to stop leftists or socdems from getting enough control of the conversation to convince workers to either overthrow capitalism, or raise corporate tax rates to fund huge social programs.

Which is all speculation on my part, but if that is the case I think the google dude is missing the point as well because all he cares about is making Google more efficient. He doesn't realize the role diversity has played politically in defending the rights of Google to its property, and so he is just a bemused technocratic neoliberal angry that he has to work with incompetent women or whatever.
