As expected, the Qualcomm enshittification of @arduino has begun. Expressif's ESP32 stuff has already been a better platform for some time... I guess I'll have to learn the ESP-IDF ecosystem now instead of the Arduino IDE.
@herzog There's some info on the open source wifi stack at https://esp32-open-mac.be/posts/ This stack is pretty cool, because it would allow the complete elimination of all closed-source code from software built for the ESP32. Already they can avoid calling into closed source binaries after the point where the radio has gone through one-time init.
As for resources on getting started with rust on arduinos, I'm not quite there yet. :P
