Maybe we can say that this is a isolated incident. And for sure it was not Ledger's fault here, but the supposedly reseller as they are the one that could have tampered it and then sell to the unsuspecting victims.
It's still very scary for users and with whatever operational structures behind Ledger and authorized vendors, if there are something wrong and made users losing money, it's not acceptable.
If it happened with CryptoBillis vendor, it can happen with other vendors and as users you will not know what will happen with your fund if continue buying and using Ledger hardware wallets.
Even if saying it's not Ledger fault, if there are other brands and other choices like Trezor, why do I have to use Ledger after this vendor incident?
Remember that users can lose all their money with one incident and don't have any financial resource for their comebacks. Safety first so it's safest to stop purchasing and using Ledger.
