The Information regularly unlocks articles for HN readers. I asked them to unlock this one and they agreed and sent a special URL, so it should be working for anyone who clicks on the link. Is that not the case?

Paywalled links in general are ok if there's a workaround. Users usually post workarounds in the threads. This is in the FAQ at https://news.ycombinator.com/newsfaq.html and there's more explanation here:

theinformation.com normally has a hard wall, which normally makes the submissions off topic here. But if they unlock it for HN readers, that's welcome!
