Don't be naive, the fact that they only recently announced that they will enable such an option, does not mean that this option did not exist in the past
I'm not naive. I've been saying that exact same thing since the day Ledger Recover became known. And I immediately felt foolish for ever having trusted Ledger in the first place.
Anyone who says what Ledger's hardware can or cannot do is either assuming or lying, and honestly I'm not sure which is worse.
No one can honestly say what Ledger hardware can or can't do, since Ledger's code is not open. If somebody says "You have to confirm any actions by pressing buttons on the hardware" ask them if they're the author of Ledger's code, because if they're not, they have no way of knowing if what they said is actually true.
Assuming a device works the way the manufacturer says it does is dangerous. If the code isn't open, the device can't be trusted.
Ledger cannot be trusted. It's up to us to explain why, because noobs can't be expected to know better. It's up to us to teach them.
