Even if the ethics on the advertiser's side could be solved, advertising as the core source of income for a business has it's own unenthical incentives imo. It ultimately boils down to more attention == more ads == more money. I'd argue we got an early preview of that effect when 24 hour news channels were coming into their own in the 90s and 00s, and the detrimental effect it had on the quality of programming and frankly truthfulness. The scale of the internet has only exacerbated those issues.

Unfortunately the industry is so large with so much money now that choosing a different business model is almost always leaving money on the table. And I don't have any ideas on how to fix that.
