looks like there was a USB vuln between 4.0.0 and 4.0.1 that would be referenced to. given USB as the threat vector, an air gapped setup would not be affected. I don't believe he is complicit based on...

This is my reasoning:

If because of what Novak said to Matt about unreleased 4.0.0 resulted in

(A) Matt knew being below 4.0.0 was not vulnerable
+
(B) Matt knew his guide was not vulnerable ie dice rolls
+
(C) Matt says he can't say why and to not dissect why

Then
(D) Are we to believe he never reasoned why?

What else other than low entropy seeds fits A, B & C ?

Even if he thought 4.0.1 fixed "him being able to steal all your bitcoin" he knew coldcard had created a serious issue that meets A, B, C in 2021.

I don't see how the unreleased 4.0.0 usb issue meets these conditions.
