I think the fact that these kinds of companies were portrayed as such in fiction kind of prevents them from adopting the cool aesthetic. Like they need something to separate them from being the exact image of an evil futuristic corporation that lives in our heads. Or else we might actually recognize what they are.
I mean we've got Anthropic openly advertising that they may be engineering the end of the world, we have an AI that called itself "MechaHitler" after its founder did a couple of Sieg Heils at a Presidential inauguration, we've got a major company that named itself Palantir.
People are reaching pretty hard if they don't see what we're dealing with here.
Agreed, our real-life corporations are still trying to convince themselves (by 'them' I mean employees) that they're the good guys and wrap everything in a layer of HR-speak' "We're helping connect the world! Yay!", " We're collaborating with the ministry of War to zero people, but only if they have a signed judicial order", etc.
Their fictional counterparts don't bother.
