I wish paywall/registration bypasses could be the original link by the OP, or at the very least, pinned at the top of the comments.

I don't understand why HN finds piracy acceptable for news content. If the post was about a video game or movie release, should we pin a link to the .torrent file?

The difference being that you don't need to play the entire game or watch the entire movie in order to take part in the discussion about that game's/movie's release. However, you do need to read the entire article before being able to take part in the discussion about that article. So I think it's fair that OPs should either make sure that the articles the post are accessible to all (and hence the discussion about those articles (which is the entire point of hacker news) is also accessible), or just don't post paywalled articles ...or alternatively post a paywall bypass. Maybe it's not right, but it's a solution.

Me too, but I also understand publishers who need subscribers so they could survive in this profit-based economy.
