No hardware wallet is open source in the full sense of the term, offering complete transparency and reproducibility.
According to you nothing in the world is open source, this is how your brain is operating.
So go ahead and use closed source wallets, since for you there is no difference with open source wallets.
You actually need to have functional brain to understand this table, but I think even average gorilla would understand meaning of this image from my table, and what Open Source is referring to hardware wallets:
I will say this for the last time OPEN SOURCE in MY TABLE is referring to HARDWARE WALLETS.

Welcome to my ignore list.
Maybe my brain isn't functioning, but you say you're referring to source code and that this is obvious, but a few lines above you're presenting the idea of a "partially" open source hardware. Which is it?
Oh your brain could be functioning oh right, but sadly not at level of a normal human being I will say this for the last time OPEN SOURCE in MY TABLE is referring to HARDWARE WALLETS.
