This surely runs in line with the industry, faults, problems, and business ideas... And has massive reason to not be in public domain...
If engineer codes are so readily available elsewhere like you said, why do we protect such info? Yet keep a topic like this on public, same vulnerabilities, same damage could be caused getting into the wrong hands.
Do people see engineer codes as a cash cow if kept secret? And before anyone says, I know money isnt made directly from this site by engineer resets, but industry wise it is... Serious question...
