> When there are few professional consequences for unethical behavior at the behest of your employer, taking an ethical stand is ineffective and quixotic. You will be fired and another engineer will likely complete the job.

I disagree. I've seen this in action where people who were CCIE-level senior network engineers at one of the five largest ISPs in Turkey quit and got new jobs elsewhere (outside of the country) rather than be an active participant in the autocratic government's messing about with internet censorship and null routing of IP blocks. These were not people who could just be replaced by advertising an open position.

The more junior staff members left behind had trouble with the government's diktat, with less clue and technical capability, and ultimately ended up implementing what was required in a less effective and shittier way than an unethical CCIE could have.
