Did you check that with an STM or how can you tell?

CH341A is made by Jiangsu QinHeng Ltd., and there's a datasheet -
http://www.anok.ceti.pl/download/ch341ds1.pdf - according to which
this CH341A has just a few config registers, no internal memory for
any firmware - and these CH341A based programmers don't have any extra
memory chips on board, that means "the evil firmware" has nowhere to
hide

Indeed TI is more open than Broadcom, but still not completely open. I
don't know any single board computer that has been endorsed by Free
Software Foundation, that means any of the existing SBCs require the
non-free blobs to function. Maybe EOMA68 could become the first.
