Arguably CUSA has created a nice case for their C64 look alike. It`s hard to find a comparable box these days.
You can' t blame a company for selling Intel chips in their hardware and Linux is a good choice if you want to add branding on an otherwise free OS. So it all rational choices here.
Let' s not forget that in the world of business today, you don' t have to earn the right to use a name. You just have to pay for it and defend it. There is no real development done by CUSA, but apparently they hired some designers for the cases and don' t be mistaken:
"Skinning" a Linux distro to the extend they where doing requires dedication and a lot of work.
