The courts already distinguish "commercial speech" as a class of speech. Would we prevent all forms of commercial speech? What about a waiter asking you "would you like to try a rosé with that dish? It pairs very well together." Is that "advertising" that would need to be outlawed?
What about giving out free samples? Is that advertising, and thus should be illegal?
What about putting a sign up on your business that says the business name? Is that advertising?
I hate advertising and propaganda. But the hard part IMO is drawing the line. Where's the line?
Whatever happened to product catalogs? Remember those? I'm interested in purchasing a new computer, so I buy the latest edition of Computer Shoppers Monthly. Companies buy ad space there, and I read them when I'm interested. The entire ecommerce industry could work like that. I go on Amazon, and I search for what I want to buy. I don't need algorithms to show me what I might like the most. Just allow me to search by product type, brand, and specifications, and I'm capable of making a decision. It would really help me if paid and promoted reviews weren't a thing, and I could only see honest reviews by people who actually purchased the product. This is a feature that ecommerce sites can offer, but have no incentive to.
