It seems Like projects like this (that include basic productivity tools) could potentially enable a small resurgence in sovereign computing. A 5 dollar esp32 is powerfulll enough to emulate 8086 architecture while running a tcp/ip stack, DVP display, and usb input peripherals.

With a simple OS like CP/M or others, a low cost computer you can actually trust to only run trusted code is possible again.

Default esp32 still comes with built-in binary blobs for the radio though iirc
