Not all advertising (especially in the broad sense of the word) is bad. There is one ad in particular in the last year that I'm very glad I saw, because it alerted me to the existence of a product that has provided a lot of value to me. Of course, most advertising nowadays is trash and the web is barely usable without an ad-blocker, but in principle, I think having unobtrusive ads for vetted products isn't such a bad thing.
