I do actually disagree there! And this is perhaps the fundamental disagreement we have. I want my sysadmin to be a capital-E Engineer and choose their ethics over my desires. Don't let me (the capitalist) tweak the bridge I'm paying for into one that falls down; and similarly, don't let me tweak the computer I'm paying for into one that gets malware, joins a botnet and DDoSes people.
You pay your Engineers, basically, to provide you the service of "knowing what's best for you"; to be your domain-specific nanny, making sure you don't do something you'll regret out of ignorance.
