We've changed the URL from https://mailchi.mp/theprepared/the-prepared-4ydgzm58vl to the article that it points to, which seems to have the most information about the story.

I don't think an issue of a newsletter which contains a paragraph about one thing among lots of other things, plus promotional padding, really counts as an article about that thing for HN purposes. It seems more like an attempt to promote the newsletter than to share interesting information about hockey sticks.
