if i allow ads on my website, i am not giving people what they want, but i exploit their naivete to make them buy what they don't actually need or want.

i probably can't even control what ads will be running, so how would i know if those ads are something i would approve of or not?

Like everything, it's a trade-off. You get money; you lose control. You get to decide whether you feel like that trade-off is worth it.
