Seeing an ad for a product or service makes me less likely to buy/use it. Luckily for advertisers I block as much advertising as I can so I may still accidentally become their customer. I don't think any of those roles you mention help me understand what is being sold. It's true they're bringing it to my attention but they'll also be lying about it to the maximum extent permitted by local laws.
