If someone is playing honest with me in good faith, and they ask for a show of good faith back, I think reciprocity, good manners and ethics favour the idea that I should do so.

If someone asks me to play fair with them, and then tries to shaft me - then any consideration I might have had for their position goes out the window. I don’t feel the slightest need to play fair with them because they are a bad faith actor.

To be clear, this is purely an opinion about ads on YouTube and whether I have to sit in one of two ethical buckets, not advocating an anything goes position.

My opinion is that there’s a third ethical position, which is a bit like the classical solution to the prisoner’s dilemma: co-operate until the other person plays you false. After that, don’t consider them a friend, and there’s no ethical problem in refusing to cooperate with them.
