I'd argue that >50% of bytes on the web are malicious. We're past the point where it still makes sense to attempt to load the page and just block the bad parts. Ad blockers are bringing a knife to a gun fight.

I'd like to find a way to crowd source an unauthorized CDN for just the good parts. Maybe the ads need to be rendered once by a server somewhere so we can extract the content from the page, but after that we ought to be able to gossip content that's been pre-stripped of ads.

The web of trust that would be needed to make the gossiping safe can also help us figure out who to pay.
