The “insidious” point is about employees, not the game, just to be double clear.
Because GH sends a positive message and isn’t sexist and so on, women wanted to work at Fullbright.
This was insidious, because they came into that expecting a positive, non-sexist culture, and were no doubt told that was what they were getting, but actually experienced some pretty sustained sexism/misogyny. Whereas they might well have simply not even applied at a company with different exterior values.
I can think of dozens off the top of my head. Shit, half the people involved in the mess at Blizzard were praised for being enormous assholes at some point in their careers. Afrasiabi and Kaplan were literally hired because they were assholes.
