As an observation, in the last few weeks are links to paywalled Science articles, like https://news.ycombinator.com/item?id=9773173 https://news.ycombinator.com/item?id=9773173 and https://news.ycombinator.com/item?id=9661641 https://news.ycombinator.com/item?id=9661641 , and Nature journals, like https://news.ycombinator.com/item?id=9661148 https://news.ycombinator.com/item?id=9661148 and http://www.nature.com/nphys/journal/vaop/ncurrent/full/nphys3366.html http://www.nature.com/nphys/journal/vaop/ncurrent/full/nphys... . Are you against those links for the same worry that those journals are paying HN and/or submitters for making the link?
