This is actually cheaper than even the recently posted WCH micro and the parts seem like improved variants of STM32F030 series (but not compatible with them). Even better, the parts are available today, in quantity from LCSC:

So much for the arguments that one can't have cheap ARM micros because of the ARM IP licensing costs.
