At this moment, you're probably mad and probably wondering what you did wrong as well as wondering if I'm just being an asshole. You're also looking at the score of your post and wondering why it is what it is; "Did he down-vote me and someone else up-voted me? Or is he just trying to make a point?"
I was just making a point, so no, I did not actually down-vote you. The thing is, you and many others have fallen, "For exactly the same traps marketers set." The trap, even if entirely fake, is the reason for the your initial anger, confusion and pondering.
This is an odd and harsh way of both supporting your point and refuting it. You are only human, so you'll get angry if you fall for a trap. None the less, you are correct; often the answer is to stop interacting with or buying from those who would try to trap you, but unfortunately, you do not always have the choice until after the fact.
For example, a newly minted MBA in Marketing needs to pay back school loans. Who has the money to pay them? Who has the job that will bring the most prestige and future earnings? The local farm selling grass-fed beef and organic products or P&G selling highly processed foods that are destroying the environment?
The marketer is going to take the P&G job and then spend their time and brainpower convincing people to buy even more processed crap.
