Hello

i will test it on a s9 (btc.com pool) and report. I would not copy or sell but i think some people here needs the answer

can we trust the original firmware of bitmain? the past has shown that we can not even with the manufacturer - see antbleed!
zwilla has found antbleed and other shit on bitmain firmware on some other miners like L3+, D3 etc.

maybe you can kano provide the firmware for testing?

the big problem is again and again GPLv3 but if originalfirmware is used without the data of bitmain to change and just add more then yes the injury remains at bitmain or?
and bitmain is not interested in GPLv3 - see all other miners ....
