Question: now that the Google workaround no longer works for WSJ links, are they even allowed on HN? @dang has implied that paywalled articles without workarounds aren't allowed.

But 99% of HN users are not going to see this and the whole reason the "web" link exists is to aid in the Google workaround, because that was the gold standard until now. WSJ has now put itself into a special class of sites. Unless I post my link on every single WSJ story submitted to HN, non-subscribers (the vast majority of people seeing it here) won't be able to read it, which means they can't discuss it etc. Therefore it would make sense to me that WSJ links should be blocked here.
There is no fair use for the copying of a whole text, and whilst the person who posts it is the one who has infringed copyright I am not so sure that you could consider yourself to not be involved.
For fora where the posters aren't inclined to paraphrase the original story, it's usually more than sufficient to paste only the second and perhaps third paragraphs of a news story; those generally contain the actual news.
