If so called “dark patterns” (subjective) are deceptive then you could argue most of commerce is deceptive. If I go to a retail store and am guided toward a product that I don’t necessarily need, is that deception? If a car salesman convinces me to buy his mostly useless extended warranty, is that deception? Where is the line?

Most commerce relies on information asymmetry. People are just picking on the tech industry because they’re highly profitable.
