I pulled a dark-pattern trick off our checkout page even though it was making us money, because it was quietly trapping people into subscriptions they didn't want. We sell things I'd tell my own mother to buy, and I want to keep it that way. If a sale needs a lie to happen, I've decided I don't want that sale.
More people experience this than they realize.
You sell only what genuinely helps people and refuse any sale that needs manipulation.
If this sounds familiar, the Library can help you find the bigger picture.
