How Ledger can scam you even if they say that they will stop support all products? You should have backup in safe place, and with that backup you can get access to your coins with help of some other wallet.

Maybe you think on some thing as backdoor exploit or something like that, that can allow Ledger to get all or some % of our seeds, but I don't think that's a very realistic option, although there is no such thing as 100% security.

Using some other hardware wallets is probably good way to reduce the risk, but if you just need to protect your coins for long-term, maybe form of paper wallet would be best option. But if you go in that direction be sure that you make such wallet in a safe environment (100% clean PC&printer, top quality ink and paper), and to wipe out all possible data after. After that you need to protect such backup, and this is not easy task - you may ask yourself what is less certain, that Ledger will somehow scam you, or that you will somehow scam yourself.

We recently have one user who is lost coins from paper wallet by using bad online service, and I also remember one user who is ask help because ink on his paper wallet is faded and he miss few characters in private key. People are losing coins every day from exchanges, hardware/desktop/mobile wallets - and in most cases due to their own fault.
