I consider that it's bandwidth issues that drive these network level adblockers. When page contents appear to be getting more ad-heavy and problems occur with plug-ins (hello Adobe..) and content (malverts) then it makes sense. After all, the customer will be paying to read the adverts in the end, and if you're not willing to pay then the model is sort of broken.
Of course this really says that the advertising model is not working, it'd be like paying for junk mail to be shoved through your letter box. If they were restricted and actually relavent to the site being visited that wouldn't be too bad, but the scatter-gun approach has just dug them into their own deep hole.
The difference between adblocker on or off can mean whether a page loads on a mobile or not. That's possibly the main issue.
