Why does the method have to come before the requirement? That makes no sense. There is no reason to develop systems responsibly if someone external has to come along with a solution to the problem you just invented.
Set the requirement. Give a fair implementation period. Then enforce.
Time and time again it’s been shown that this works, no matter how many times organizations squeal about it being impossible.
Better still. If basic standards of ethics were imposed then tech bros would have to develop with those in mind.
