Avoid if you are just about buying a new hardware wallet. As for safe, if you were already using Ledger before they announced the Ledger recovery service, you might just continue using it as you have been doing so, but of course without 'subscribing' to the new Ledger recovery service, but whenever you decide to get a new hardware wallet, you should ditch Ledger for a different brand; because there is then no reason to continue using it.
If it is open source and you can't verify the code yourself, i think you should at least wait for others who can to verify it and see if there are complaints about bugs/malicious lines before you update yours.
