Imagine a device that looks like a calculator. When you type 2+2, you get 7. You could conclude its a broken calculator, or that arithmetic is subjective, or that this calculator is not doing addition at all. Its doing some other calculation.
Imagine a robot doing something immoral. You could conclude that its broken, or that morality is subjective, or that the robot isn’t thinking about morality at all.
These are just different ways to describe the same thing.
Addition has general rules. Like a+b=b+a. This makes it possible to reason about. Whatever the other calculator computes may follow this rule, or different rules, or no simple rules at all.
But reasoning about morality? Is that a space with logic or with anything goes?

Not to the extent that there’s no difference at all...you can exclude some of them on further investigation.
