Ads succeed when you "tune them out" so that they enter your unconscious mind, and then when you're thinking, "I'm hungry, what's for dinner," the product comes to mind.
The best defence against this kind of inception is to consciously think about the ad that's playing, and think, "I don't want <X>"
By using adblock, you reduce your exposure to ads, and reduce the number of times you need to consciously resist them.
Q's take is just wrong.
