I don't see the distinction. Everything but shears removes material at the cut. A plasma cut is no different in that respect from a saw, grinder, water-jet, laser, torch.
Cutting something with scissors, or in the case of thicker metal a press with a bit, doesn't remove material. Tearing something in two doesn't remove material. But you're right, any sawing type cut, as with a grinder, does remove material.
What I was really getting at though is that if you look at the definition of "cut" you'll see in most (all?) sources it defines it has being achieved through a sharp object or tool. I understand that's not often how it's used colloquially though.
