Somehow, this simply doesn't surprise me. During my career, I've had to deal with Chinese manufacturing. I have to admit that when someone asks them to copy another competitor's product, they do copy it well, right down to using the competitor's logo.
It happened at one of my jobs where I was just there for about 6 months and had no idea something that corrupt took place. I got a call from the competitor, who was dialing around, to find out what the hell is going on. So I started asking around until I was told to just redirect the calls to some head honcho.
I was also told that what the competitor was doing was incredibly unprofessional, which I have to note is rather ironic. Are they telling me it's more professional to steal another competitor's design, replicate it, and sell it as our own?
