It reminds me of when Honda threaten to sue reproductiondecals.com if they continued selling Honda decals. It may sound strange to us, Honda fans, that Honda would hinder somebody offering decals to restore our bikes.
But corporations, specially big ones, are not driven by feelings. Their point is that an external company is making decals with their designs, and if we pay $3 for a Honda decal, $2.99 is for the design and $0.01 is for the material -you get the point-. That is, we wouldn't be buying a decal from that company, has it not being for the design on it. Therefore, a Honda asset -the design, the brand, the image, etc- is being used by an external company to add value to their product -an adhesive sheet-, and Honda have the right to protect their assets. After all, regardless of how deeply you want to have decals on your bike, the fact is that they don't add any value to the product -bike- with respect of its primary function -riding-, and there is no way to justify the necessity of circumventing patent rights for selling reproduction decals.
