That disingenuous, ignores what I wrote, and compares two different things. Ads may increase sales, but ads don't force people to purchase products.

That's true, which is why there are food labels and lists of ingredients. However, ads don't make people purchase anything.

Of course ads exist to increase product sales. That doesn't mean that people are unable to actually look at the product label and make informed choices. Ads don't make you do anything. Thinking that they do is a crutch.
