The New York Times is another one I can think of. I'm not against pay walls or ad blocking, but if, as a content provider, you choose to implement these sorts of "devices" than you can at least expect your content not to be shared around any more on link sites such as HN, i.e. you're not serving the community on those websites any more, your serving your customers. Which is fine, but I'm not your customer.
When ever I see a pay wall on HN these days, I "flag" it.
