I have been in that situation in a startup. The boss would come to me and ask for some dark pattern (not cookies, I don't remember exactly what it was). I said I wouldn't do it. They literally asked a guy in the adjacent room, and he took it as a new task and did it.

He was not a bad guy: I did not care about getting fired (I was young and single), he did (he had a family). And in his opinion, if the boss wanted it, anyway it would end up being done. His job was to implement what the boss wanted, not to contradict the boss.

Both understandable and good that you stood up to it!

Sometimes though bosses need some contradiction, for the business to be successful. It is not the best approach to have no opinions or ethics.
