I'm of the opinion that advertising is immoral.
To be clear, I mean active advertising, in the sense of placing product information out of context. That includes billboards, products in movies, commercials between songs or before movies, and most of the crap that shows up in the mail. I don't have an issue with passive advertising, for instance having "the special of the day" on an e-commerce site, or related product information such as offering me different vehicles if I am visiting a vehicle sales site.
Active advertising is literally coercion, enticing, manipulating, and encouraging a viewer to make purchases that they otherwise do not wish to make. "If only you knew about our great product" does not justify the psychological arm-twisting advertisers undertake. Yes, by the end of your advert I might "want" your product that I'd never heard of, but as the OP says, "fuck you". You are taking money out of my pocket that I did not plan to allow its removal. In some circles, that's theft.
