Thought experiment: assume in an alternate reality that coldcard found this bug before the hackers did. How do you handle it? As soon as you announce that a seed generation bug is fixed to the general public, you are going to have the same race conditions as right now. The bug is just too trivial to find once you know it exists. And just getting everyone on the latest firmware doesn’t fix it. So you can’t just slide the fix in unannounced.
