Ledger Nano X, S Plus and S are not affected. Are there people that are still using the old type of Ledger Nano? Is Ledger still supporting those old devices? I do not think so. I will not recommend anyone to use those old devices anymore. At least, you can get yourself either the X, S or if you are NFT person, S Plus.
Why would people NOT still be using them? If they work and did what they needed to do there would be zero reason to replace them.
As for support, it should matter. Devices like this should start out secure and end secure. If there is something like this found then ledger should fix the issue if possible even if it's not supported.
And lastly, now that they found the issue, would you really want to give more money to ledger for another product or try another brand?
