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.
