Sorry but how is sharing a link to my followers on Twitter, or my close friends on Facebook different from sharing a link on Hacker News? Original content will always want to be free to make as much money as it can. NYTimes for example will publish a URL for sharing, but also have an Apple News exclusive URI that forces you in that app sandbox. One thing I love about Facebook sharing is the commentary and comments below the content.
