We could all use some education on how to use the ledger and the trezor without their platforms. The
Even if one starts to use the hardware wallet without their platform, I guess having even once used the platform means that their servers can easily connect that address with the said device delivered to a particular address and customer?
So that renders the whole thing traceable forever I guess. I would be happy to know if someone can give information to the contrary.
I use my Ledger with Electrum using my local Electrum server linked to my own Bitcoin Core (yes, it means 425+GB spent for that). I even
wrote a tutorial for it.
Of course that if you've used their wallet, your addresses will be traceable, at least the first some (10-20), so best is to reset to new seed.
And of course that (especially in case of Ledger, since it's closed source) one doesn't know 100% sure his addresses are not tracked even if he resets it and never use the wallet part of their HW platform (since the info may be already leaking at firmware updates or installing the bitcoin app into the HW). You can follow
my answer here and maybe that whole topic.
