In other words, do you think Ledger has already got something akin to a master list of every Ledger user's private keys? Just thinking out loud here, you know?
We wouldn't know for sure if such a list exists, but since they said that their users' keys cannot leave the secure element, but it turned out to be a lie, then anything is possible with ledger and it is surely not a recommended hardware wallet. They were also caught lying that they are on an open source roadmap
[1] which isn't true, too many lies coming from Ledger and it is enough not to trust them. A company can layoff staffs without any ominous meaning to it, but one that has recently come under fire and have probably lost all their customers that understands a thing or two about security, then it could mean something extra.
