That’s a nice fantasy, but the number of ad-blocking users and ratio of advertising revenue on mobile (where adblocking is harder) vs PC suggests to me that the content of ads doesn’t affect user experience nearly as much as the quantity and intrusiveness of ads. I think the second part of your sentence is the real problem being addressed, nothing about advertising is actually designed to directly benefit consumers. I think you would be hard-pressed to find people who actually factor ad relevance into their enjoyment of an ad-supported product.
