It's all for sales and nothing more. Those who supply them don't care what happens to the plants as long as they get bought. It's like going on ebay and seeing purple or blue watermelons from China or Japan or other areas. It's a gimmick. Unfortunately, those that buy into them, have no idea that they'll most likely be dead in a short time. I think their horrible, like the orchids that get dyed or roses, or even Poinsettia's with glitter. It's all about sales.
