Lets take the most basic form of advertising as an example. If I put a couch in my yard with a price tag on it, I'm wanting people to notice and desire to buy it, but there's no malicious intent. I have a thing I want to get rid of, maybe someone wants to buy it. If I don't do that, no one will know it's for sale.
So I do think advertising is fundamentally benign, and despite what the original comment said, is absolutely part of supply and demand. People are supposed to generate supply and then sit around waiting for people to come see it?
Of course there's lots of bad stuff going on in advertising. Lies, inducing FOMO, unnecessary gathering of personal data, etc. But I'm not convinced that advertising is morally wrong in it's purest form.
