I've seen a number of ESP32 IoT devices here on HN, and I haven't heard many of them use firmware encryption with an eFuse.
In this case, it would have been pretty hard to create a certificate if you couldn't read the firmware.
But, also pretty impressed at the same time. I think this is the first Hacker News article I've read about an ESP32 IoT device which has any encryption at all.
