As we know Private keys are generated only Once on every hardware wallet while setting up.

We can't generate it many times as we want, if that fixed one generation of key while setting up every hardware wallet are already compromised?

How do we trust anything or anyone that it's a complete random generation, we are not in it we are trusting manufacturer's? It's like trusting third party? If any force make them cheat on it how can we protect ourself because people are trusting hardware wallets blindly thinking its 100% safe many have lifetime saving's on it !!  

There maybe possibilities of having loopholes while connecting to software's how can we trust it if they are created under any force?

How manufacturer's come out of these issue's ? what should be the next invention to protect crypto for getting more decentralised.

Questioning is the only right way, we should focus on appreciating questions to bring crypto to next level.
