Coinkite explains why it destroyed affected inventory, stating that COLDCARD's high-security system locks prevent re-upgrade until the user initializes the device. It says shipping units with affected firmware would risk users missing the upgrade, so the safest action was to destroy affected stock and ship only devices with the new fixed firmware. Held as a vendor incident-response statement.
