The HN convention is that paywalled sites are fine as long as there's a way to bypass the paywall - usually by browsing to it via Google, which is easily accessible from the "Web" link below the title in the post's comments page. Posts to pages behind impenetrable paywalls get flagged into oblivion. Why does it happen so often here when anyone submitting can easily find a non-paywalled source with the same information? Because this usually isn't the case at all. Quality of sources varies considerably, and HN always wants the best one.
