How does that even affect funds recovery though, because the Airgap tools are open-source so there is no risk of them disappearing anywhere (as opposed to, say, an exchange or closed-source wallet).
I didn't mean disappear with your money and take it from the users. They said that their scheme and implementation isn't compatible with anything else. So if you set up a social recovery option on AirGap, Airgap is the only software that works with that system. Electrum is open-source, but you can no longer connect old versions to Electrum servers. It's for your own security, but I am just making a point.
My question is what is going to happen with a scheme that is incompatible with any software/hardware wallet we know today if tomorrow everybody at AirGap abandons ship and the wallet simply dies? I got the answer that someone would have to create their own software supporting the social recovery feature and hope it works. That's what I expected to hear as well.
