To be honest: I don't know for certain, but I'd assume that the people who pay the bills get the strongest alignment. They may not be tech people, but I (so far) haven't got a reason to think that the AI engineers are going behind the backs of their corporate leadership and subverting what they're being asked to do; do you?
(I think it would be a good thing for humanity if they did)
I think right now both the engineers developing AI and the share holders are more focused on beating coding benchmarks and gaining revenue than anything to do with alignment.
