I'll go out on a limb and answer that on Dan's behalf: Yes, please post these links in the comments. They are a benefit the community. Dan's needs to walk a fine line between having working links and not being sued by evil companies. This is what he is referring to in some of his comments when he mentions 'lines that should not be crossed'. He can't (read 'would be wise not to') offer you blanket permission in advance to post such links. The link may even be removed in the unlikely (?) event that HN receives a threatening letter from Elsevier, and at that point, a policy may be loudly proclaimed. But until you are explicitly told not to, please keep posting the links that let people read the publicly funded research.
