It doesn't seem like you understand what a supply chain risk designation is for.
It's to ensure that companies that the DoW relies on don't build on top of a product that isn't fit for DoW work.
You seem to be agreeing with this designation in a way. The DoW essentially said "Pen company won't let us use their pens as neutron-flux regulator rods, so anyone building power plants for us isn't allowed to use these pens as neutron-flux regulator rods".

What is the problem you have with that?
