I don't really understand why the culture of some companies is something that needs to be fixed. As long as there's nothing illegal going on (like harassment), then what difference does it make from the outside whether a company has a toxic environment?

If women don't want to work at those companies, that's fine.

I'm not a woman, but I don't want to work at those companies either, and that's fine too.

Is there anything stopping 'sis culture' companies from being formed and dominated by women?

Or companies dominated by people who make everything about video games or sports or chess or cosmetics.

Some of these companies will succeed, most will fail. As long as no one's getting harassed, why should we force them to have this culture or that one?
