You didn't remove the inflammatory wording, you quietly swapped their argument for a completely different one.
Coupons are not the same as surveillance pricing, because coupons only adjust the price down. They're the way manufacturers get people to try products they wouldn't have bought otherwise. Very importantly, coupons are used by very few people, most still pay the retail price, which forces that price to still remain competitive. Also, anyone can choose to use or not to use coupons. Surveillance pricing is a mandatory price cut or hike that's assigned to you personally by seeing how desperately you want an item and how much you can afford to pay. It's just abusing your customers for the last scraps of cash they have left in exchange for the same product.
Member-only prices are closer to surveillance prices because they make you trade away your purchasing and location data, or even enter some kind of a financial contract with the company, in exchange for a lower price. But it's still nowhere as evil because most people still pay the normal retail price, so the difference between the two prices can't be too disconnected from reality, and because the hoops they make you jump through are still technically free, so it's not dependent on your ability to pay.
More relevantly, someone who sees $70 for a chocolate bar and has a $69 off coupon probably won't be back to "that store with the stupid prices."
