Re easylist, that is what I meant by 'pretty obvious'.
Re first party advertising, the scorched earth blocking approach is going to push the advertising industry to take over first party advertising. Your site runs httpd and advertd, where advertd receives ads from the industry to inject into the pages, and returns tracking data to the industry. If this doesn't exist yet, it's definitely under construction.
Also first-party advertising is complicated because it prevents the advertising company from publishing the ads it wants, since the ad would be delivered by the site itself. While this is the business model of Google and Facebook, most sites don't have the analytics power to publish the most relevant ads to their users.
