Any reference of this being admitted?

Yes there is an entire What Bitcoin Did interview with the CEO of Ledger where he explains they can access your keys 😂 DYOR

A Ledger spokesperson refuted that, saying, “Customers can create an encrypted backup of their private keys which is then sharded and encrypted further […] The private key can only be decrypted and reconstituted on a Ledger’s secure element chip, just as it is initially encrypted and fragmented there. Ledger cannot and does not access users’ private keys.”
