TFA says this one isn't STM32 clone though. Just the peripherals are similar. Not sure about ARM license.

  > Not sure about ARM license. I wouldn't be surprised if that's legit. The Cortex-M0/M0+ core is fairly inexpensive to license and use. It's effectively a loss-leader for ARM.

    Why would it be a loss leader? Surely it's because 0.1c X a bajillion chips is still a lot.

      Because there are a lot of other tiny microcontroller ISA's, and there isn't much value in using one over another. If they charged much at all, then people would just use another.
