The main point of it that I took away from the article is more providing the manufacturer with a way to distingish their product with clones or grey market products–so they can support just their product.
There’s no scarcity for products like these. They’re readily cloned. All that’s being done here is making a way to provide a means for the manufacturer and the customer to know that a specific board is legit.
You can clone the thing to your hearts content, Bunny probably doesn’t care. He just doesn’t want to have to support clones someone else made nor does he want to have to replace broken boards that he didn’t make.
That seems completely legit.
