I think the better analogy is an insane nuclear power plant manager deciding it wants to buy pens to use as neutron-flux regulator rods — because after all, a pen is functionally a pencil and a pencil is made of graphite.
Then the pen manufacturer hears about this and says “Our pens are not made of graphite and are not suitable to be used in nuclear reactors”, to which the reactor owner says “it’s fine, they fit in the graphite rod holes, and we’re just using until the next generation of pens come out which will do an even better job”, and then the pen manufacturer says “I’m not going to sell you any pens until you agree that they will be used only writing.”
