There are several motives for why they are like this-that:

1. There aren't a lot of women in the computer science area, much less in games, mostly because of oppression and stigmas. Even if woman stood up and point to their bullshit, they just abuse them, like when a woman asked about beauty standards in WOW, and well see by yourself.
2. Other most video games companies are the epitome of liberal philosophy, they want to make the more money for less work without any kind of shame; exploitation, abuse, underpayment, directly lying to millions if necessary. It's crazy how this companies work.
3. Video games are a golden mine to government (thus Nazis); campaigns to recruit people to the army, to past ideologies like the communist are evil or war is necessary or China bad (LOL), harassment, and psychopathy are also promoted, and a lot of mental system to make the player an addict.
4. Anglo world is the biggest gaming market, so you know, scratch a liberal and so on.

A few hundred o even millions of “gamers” are aware of the greediness of companies and criticize it one example could be the case of blizzard and all their recent actions. And the smaller games made by normal people are a lot more progressive, even some big ones have crazy takes…
