What's the old saying, "when you lie down with dogs, you get up with fleas." It wouldn't matter to CB if the Noj design was copyrighted or not, if they can see their way to making a profit, ethics be damned!
Even if they are stealing other peoples' designs, do you really think anyone's going to bring suite against them in an Indian court?
I know some people didn't like the idea of chessbazaar from profiting on noj's initiative and work in developing the Tal set. But noj jacked up the price several hundred dollars since it was first introduced...almost beyond reach for a man of ordinary means. The finish on the pieces though, is first rate, and I don't think chessbazaar will match that quality, so I don't think cb would be able to take over the market for this set anyway, and NOJ's ability to produce sets is limited anyway. Anyway hope you guys aren't mad!
