The difference is Sam is just your regular soulless sociopath CEO, we're used to them.
Dario is just a profoundly weird freak, who is obsessed with trying to cover his endless greed in messaging of safety and "alignment" even though every single fucking thing he does is diametrically opposed to them.
He literally named his company after humanity even though his main messaging this entire time has been that the technology he insists on developing will a) destroy the world b) leave us all jobless on the street before it does.
Just revolting hypocrisy and projection.
