There’s also the fact that I have RP2040-Zeros ready to use in a drawer. They’re so convenient, tiny, cheap, still lots of pins, always enough performance, easy to program with just a USB cable. Any other MCU, and I’d have add power regulator, caps, coils and a USB connector. Add the cost of shipping from Mouser/Digikey (at least $5) or LCSC (long wait time) and it only makes sense for high volumes. IOW: never.
