I suspect it won't be long before ad networks supply self-hosted proxies in multiple languages for sites owners to use. Or, since ad blockers primarily use DNS names, ad networks could simply add CNAME support to their infrastructure. Granted, either approach would injure the ad networks' ability to track you, and expose those cookies to the site owner, but I would suggest that fingerprinting tech is mature enough that proxying the request won't prevent the ad networks from correlating identities. It's cat-and-mouse. We're enjoying the benefits of a faster, safer and cheaper web (as are the developers behind those content sites using the ads, I reckon), but my prediction is that those benefits will be short lived. There are cleverer people than the browsing masses, they will find a way.
