I mean, nothing changed about them as airgapped signing devices aside from the RNG issue. There are a few things the RNG gets used in but they're lesser used features. Key teleport, hsm, that sort of thing. Many are migrating out of an abundance of caution, but I haven't seen anything detailing an attack vector that applies. We do know more about their sloppiness and poor testing though, so that's enough for some I guess...
