They don't have to. You can say they aren't...sure. You can help your argument by showing me any articles or advertisements with a mention of spider silk or bulletproof clothing....prior to KBLB's breakthrough. Why would they? It wouldn't be and wasn't on the RADAR. KBLB put these on the marketing plate, and these marketing geniuses are jumping on it. They know what is coming and Spider silk, or its properties(bulletproof), is an easy sell. They even found a new marketable use for kevlar, by putting it in clothing.
