Re: No I don't
"a) I'm not going to buy anything as a result of an ad on a news site. Usually I buy by browsing a shop, eBay, Amazon etc or searching for something I've decided I want. I never click, so no revenue lost?"
Of course the reason you decide to buy something might be because you've read about it on a news site. If the news site blocks you for using an adblocker it's the advertiser who loses out in the end. Funny old world, isn't it?
