This website redirects away from the article after a short while if you run an ad blocker. I won't turn mine off, for reasons that ironically have to do with a distrust of third party tracking networks.
I see this comment all the time, what people often fail to realize is that if you won't turn off your ad-blocker, the website doesn't want you. You cost them a small amount of money to deliver the content (bandwith) and they invest a modest capital into creating the content (paying writers, etc), and you offer nothing in return.
This doesn't mean you have to stay; if this behavior annoys you, don't read their content. But don't complain that their website is "sending you away", because that's exactly what they want. You laid out your demands (ignore the fact that I'm using an ad-blocker), and they're showing you the door.
And that's just fine too; there was an internet before these guys, there will be one after.
But, it would be nice if there were some way to filter out sites like this one, and others that have interstitials or the infamous "Forbes Thought Of The Day" and all the other nuisances.
Because I don't want to be on their site any more than they want me on their site. They just keep showing up in my various news feeds.
I think people are fully aware, but they're claiming that sites do not have unique content or provide other value that would be enough to justify display of the ads, or they think that all sites should always find non-ad based revenue streams yet provide open access.
Personally, I make a judgement call. On the Atlantic I got the ad block message recently and decided to switch it off as I find the content unique and well-written. They're not a news-aggregator or a spammer, their ads aren't that intrusive... I think it's a fair-call.
That's not a "class" of customer, that's a status of being/not being a customer.
Class of customer, in the sense of the question, is a visual attribute of a customer making them unwelcome due the low probability of them being profitable for the store.
I can imagine businesses simply prohibiting the use of the toilets to people who don't buy things (“restrooms for customer use only”), which is a closer analogy: it's not about a retail store where you are browsing and may or may not buy, it's a place where you “buy” or not (by accepting ads) when you enter, and your access to other facilities is conditioned on that decision.
EDIT: NoScript did the trick.
