I would like to see someone challenge ads and/or ad blocker blockers in court. They're a huge waste of resources especially on mobile: bandwidth, battery life, etc. Bandwidth is very expensive on mobile especially outside the USA.

This uninvited use of your resources is stealing. I think you could make the case that all of the resources wasted by visitors is more valuable than the website is generating via ads (or losing from being blocked).

There would be many hurdles to cover especially due to all of the technical details (you requested a resource, they just served it) but I think you can argue that when you click a link to an article the user intends to request the article not the junk they're forcing you to have with it.

It actually would be nice if Google ranked pages by page size or had some way to tell you what you were in for by clicking on a link in your search results...
