not by what was described in blog post coldcard was an entropy generation fail because they rolled thejr own RNG protocol

No, unrelated. That one was a random number generation problem in another vendor's device. These are issues in our own firmware, found during our internal audits: a bootloader exploit already fixed in July, a memory corruption bug on the Multi edition, and a silent payments implementation issue that could have locked funds at an unintended address. Different code, different companies. (You can read everything in the post)

Probably not, but it made them reinforce their ecosystem with more audits and fixes, like everyone else…
