My issue with this view is that the viewer makes himself seem like this victim. Let's put ourselves in this scenario again. You, the viewer, are on my website. You're using my server bandwidth while using my website functions, which probably had a lot of investment go into them whether they were services or content. Multiply you by a 1,000 or 10,000 or 100,000 and now we have a problem.
This you take for granted. This you don't pay for.
It's my website. I choose how to monetize it. If you like that, great; otherwise, stop using my website. Until we generate some automatic way of blocking you from ever using my website while you're on AdBlock, then what you're doing is stealing. No one forces you to use my website.
A lot of examples in the real world apply here. There are adverts on highways, buses, buildings. Removing that clutter-creating huge banner ad from the middle of the mall; how's that different from removing a leader-board from a blog?
How can removing ads completely and automatically - from websites that earn their entire existence from adverts - while still accessing the website's content and using their server bandwidth anything less than a cowardly immoral act of theft? And to hide behind that as some sort of hero for having the mental capability of installing AdBlock is just downright delusional.
Blocking advertisements from people that live off of them while still using their resources is theft. Plain and simple.
