My issue with the replicas isn’t the price, or who makes it, or the quality. It’s how someone is making a fast and dodgy buck by taking advantage of a designers work.
It’s one issue if an object is in the public domain, and someone makes a shite version of it, but still plasters the designers name all over it. I don’t like it but it not illegal. At least the opportunity exists for someone to make a quality version of it.
It’s another issue if a designer gets ripped off, with no compensation, and has their name linked to a shoddy product, that they have no control over.
