Ars Technica argues that ad blocking is harmful to the sites you love.
If you read a site and care about its well being, then you should not block ads (or you subscribe to sites like Ars that offer ads-free versions of the site). If a site has advertising you don’t agree with, don’t go there. I think it is far better to vote with page views than to show up and consume resources without giving anything in return. I think in some ways the Internet and its vast anonymity feeds into a culture where many people do not think about the people, the families, the careers that go into producing a website. People talk about how annoying advertisments are, but I’ll tell you what: it’s a lot more annoying and frustrating to have to cut staff and cut benefits because a huge portion of readers block ads. Yet I’ve seen that happen at dozens of great sites over the last few years, Ars included.
They also ran an interesting little experiment: for those running ad blockers, they also blocked the content.
