I had success programming Chinese clones of the STM32F103C8T6 aka Blue Pill by just changing the device signature the programmer looks for via a flag in openocd. Fortunately these blue pill clones behave identically (so far, in my experience) to the real thing and are abundant and cheap on eBay so might be a good option for those who still want to work with a STM32 chip.
