In my experience, it's often the other way around. They'll say that because everyone else is going to replace certain jobs with AI, they'll have to do it, too, to stay competitive. If they don't stay competitive, they might need to fire workers anyways.

In theory, I could imagine someone employing AI, while from a moral viewpoint supporting a ban of it. One problem is that such a ban would need to be universal for it to not put anyone at a competitive disadvantage, which we can't achieve with national laws.
Well, and the other problem is that most people who argument this way then get massive bonuses and also pay bonuses out to investors, so that completely undermines any potential for morals.
