I say this with all due respect.

Prove the Ledger Nano doesn't have any of the code that enables Ledger and other companies to gain access to the user's seed.  Don't quote Ledger.  Ledger has lied many times about many things, so the value of their word is zilch.  Prove it.  You can't, which means the device can't be trusted.

That's the difference between open source and closed source.

With open source code, if somebody has doubts, you give them the link to the code.  It's all there, published for the world to see.

With closed source code, there's no way to prove anything.  And since Ledger has lied so many times about so many things, anyone who trusts them is either ignorant, meaning they don't know better, or they're just plain stupid.  Ledger had to scrub their entire website to remove lies.

Too many people trust their Bitcoin to companies that lie to them, and Ledger is the worst of the worst.

No Ledger device can be trusted, long term.
