Yeah that's one of the main issues with inventors etc who invent most anything now. They have to shop around and get quotes from manufacturers to set up and produce thier item. It's typically too expensive to do here in the USA. So they'll fly out and ask 10 or more manufacturers in Asia for quotes to make thier item. They all can simply refuse and choose to make it themselves after getting literal detailed information about the item.BINGO!
Which is why I never wanted to manufacture anything... build a factory, etc. Just wanted to license it to someone already set up to do all that. Just send me the money : )
I've even seen how China was basically giving away routers to even our military so they can monitor everything that goes thru them. Which kinda seems obvious but they ate it up apparently
