I recall reading that to and it was debunked years ago.

Hence why i wrote "WITH A PASSPHRASE" in my comment :)

The seed cannot be extracted if you use a passphrase even with that multi-millionaire hardware tool kit :) Just like the files on your computer can be extracted without using a password.

The link you posted was from their inferior competitor ledger website. Ledger leaked private user data to the dark web. Ledger also has the ability to download your private keys to the cloud. This is not possible with trezor. Here is the article that explains it. Since your link was from their competitor, my link will be from Trezor :)
