When someone on Lesswrong uses the term 'simulation', they are probably making some implicit metaphysical claims about what it means for some object(A) to be a simulation of some other object(B). (This particular subject often falls under the part of metaphysics known as ontology.)
The same applies to usage of most terms.
Correct me if I'm wrong, but "They are probably making some implicit metaphysical claims about what it means for some object(A) to be a simulation of some other object(B)." and "They are probably making some implicit claims about what it means for some object(A) to be a simulation of some other object(B)" mean exactly the same thing.
