Can someone provide a link to a non-paywalled version of the article? Or better yet, suggest a way so myself and others can find non-paywalled versions in the future on our own?
I specifically avoided using a WSJ link on a story that made it to the front page last week because of the paywall, and it was changed to the WSJ link by HN admins because of the "original source" policy. I wasn't particularly thrilled with this because I don't want to encourage paywalls, but apparently they are going to be a part of HN for the foreseeable future. So get familiar with the "web" link - you'll be using it a lot.
Edit: for the future, you can just type "archive.is/" infront of the url.
