Their products being closed source is just mind boggling to me. We cannot know if they have a backdoor. And they even provide a feature for cloud backup, so if a backdoor triggers that, it would go totally undetected. https://walletscrutiny.com/hardware/ledgerNanoS/

I know people that have ... well, Ledger themselves claim that a backdoor is worth $260.000.000.000US. Those people I know hold peanuts in comparison.
No way!
