Software engineers don't understand they're not professionals. I mean, they describe and think of themselves as such, but they are not legally such.
Being a "professional" legally means that you're given exclusive rights to perform some economic activity and in return for this (usually) lucrative right, you have a great number of obligations - being responsible for your work (ie, facing the possibility of never being able to perform said economic activity legally again), an enforceable code of ethics, an dispute / resolution process etc, steep fees, continuing education, an accreditation exam, etc.
Software engineers by and large do not want the obligations and restrictions of being a real profession, so no, they don't have any special ethics or rules to report or do anything in these cases beyond what a designer or secretary would do.
