How was this missed? Daft question.
It wasn't missed. The locks are intended to be sold to clueless idiots, not intelligent people. There is a vast market of clueless idiots, but not quite so many intelligent people. Who would the proverbial thinking man choose to market at? Especially if you can build a product down to a price, and then mark it up several thousand percent? It might be a short-term market, but the near-term profit should be magnificent! And the best thing is, that with a simple re-design and a slightly different buzzword filled marketing campaign you can sell it again and again! And it's perfectly legal. Cool, eh?
