My guess is that the ‘secrecy’ is because the ‘technology’ is so simple and could be built in anybodies’ garage with off-the-shelf- parts. The Chinese are going to steal it, that’s a given. The rest of the world will makes them on their own using whatever scheme they can to copy it. The Rossi Group wants to make as much money as they possibly can as fast as they can before the design gets viral on the internet and every redneck on earth has one in their back yard.................
Eventually some guy finds the switch and turns it on.
You rely upon trade secrets when you are confident that you can protect your franchise by keeping it secret. If anyone can do it, then your only recourse is to patent it. The way you patent something is that you disclose it, which is what patent means. So, this argument in defense of their secretiveness is total BS.
