How could it hurt to look at them?Like Rolf, I thought that this utterance on April 1 deserved fortune enshrinement. It reminded me of one of my favorite articles: "P-Values are Random Variables". Unfortunately a legal copy of that paper is still behind a corporate firewall for which you would need to fork over USD 50.00, but a google search for "P-Values are Random Variables The American Statistician" should yield options for the less squeamish.

(My copy was obtained when I did have legal access.)How much did money or do the authors of that paper receive in royalties? That's important, because the purpose of US copyright law is, "To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries." (E.g., Wikipedia, "Copyright law of the United States", "https://en.wikipedia.org/wiki/Copyright_law_of_the_United_States") Very few if any refereed academic papers are written for financial gain: Lawrence Lessig said that congressional representatives rarely hear counterarguments to the garbage they get from corporate lobbyists. The Trans Pacific Partnership (TPP, and probably also the Transatlantic Trade and Investment Partnership) will strengthen the rights of corporations in this area. If you think that will limit the progress of science and the useful arts, as I do, I suggest you contact your elected representatives and tell them so -- if you are a citizen of a country with elected representatives. I think we should also ask the American Statistical Association how much money they make from that and what it would take to put all that material in the public domain. I think professional organizations should come out strongly against these provisions of US copyright law and trade agreements that strengthen rather than weaken the stranglehold that major corporations have on the intellectual heritage of humanity. This relates to R, because R is based on an assumption that the dissemination of publications, articles and software, for which the authors are not remunerated from copyright proceeds should not be limited by pre-internet rules that stifle unnecessarily the distribution of knowledge and with it improvements in productivity and economic growth.

Maybe it's not the article itself for sale. Sometimes a company will charge a fee to have access to its knowledge base. Not because it owns all of the content, but because the articles, publications, etc have been tracked down and centralized. This is also the whole idea behind paying a company a few dollars to do a semi-extensive background check.
