Why is this practice allowed? Seems like every article that gets posted here has a link leading people to a non-paywalled version of the article. Does this not violate one of the rules of HN? Or I guess I'm asking, shouldn't it?

In the guidelines it specifically says "It's ok to post stories from sites with paywalls that have workarounds." This feels weird to me because it's encouraging piracy/unauthorized viewing of paywalled content. Particularly in an age where media businesses are struggling to compete and many have instituted paywalls in order to financially support quality journalism, why is it the policy of this website to tacitly allow users to get free access?
