It's been proven that most hw&sw wallets and exchanges are run by scammers.
Would you like to get these answers? Would you really want to respond you that same way? If you're trying to convince someone, at least, provide some arguments. So, from the whole post I wrote you, you answered that the majority of HW & SW wallets are created by scammers. Not a surprise you aren't taken seriously from this community.
As for the wallets, I highly disagree if we're talking about the open-source ones.
If you do not trust the entropy generated by your kernel, then you shouldn't trust the device that you're using.
I believe that there's a difference between trusting your device and trusting its RNG. For example, if you roll your dices and derive your addresses like so, you do know that it was a completely random choice of entropy. You can try it on other devices too to confirm that your main device won't “betray” you. But, if you do this with the RNG, you have no proof of your randomness.
