Yes, it might put those sites out of business - the websites which rely solely on web traffic use fake titles, sensationalist headlines, click baits, troll baits, fake news i.e. most of what is wrong with the internet. It harms them in the short term... and the most evil company in the history of the world in the long term. I see it as win-win.
Again, no. How do you think nearly all small legit websites that aren't being bankrolled by a single passionate person stay up? Ad revenue.
As an example, PortableApps.com isn't exactly small, but without ad revenue I'd shut it down. It doesn't make enough in donations and a handful of drive sales to survive.
Ideally we'd find other ways to bankroll websites. Obligatory snowdrift.coop plug here (best intro, though with outdated visuals, remains https://wiki.snowdrift.coop/about/intro )
Why not sell display ads that are relevant to your target audience? Use pay per impression instead of pay per click. (To the extent AdNauseum succeeds, pay per click won't pay well anyway)
If there were an ad network or agency that did this with a similar level of revenue (or even just close), I'd switch. There isn't. I've looked. For years. I wish there were.
