That's just one project that's makes poor design decisions with big claims.

ESP32 is not a secure platform. But it's cheap. So they made a trade off to at least call their servers for security. Not my preference but works for some ppl.
It's better for us all if NVK spend his time protecting the private keys of the coldcard firmware signing. Bc if those get out, we are all holding ROOTED coldcards. And which might have already happened. 🤷
100% - the hardware should be completely open. it's so low requirement, really, a commodore 64 could do the job.
