And you'd be right, that Valve is nothing special, if that idea is correct, because in that case most companies will be like Valve. But just look around, do you see many companies like Valve? No, that's because capitalism is bullshit and that makes Valve stand out.
i guess Yanis Varoufakis did work at Valve, so there's some basis. but then again, what an organization is internally and how the organization behave as a whole can be different.
