But this is the point: he made something freely available that is supposed to be freely available. The individuals publishing do publish because they want their papers to be read and cited by others. Unfortunately there is hardly an established free peer reviewing system available, so most research results are only available to a small elite. Being no student anymore, I cannot afford reading most papers because $30 to read one paper is too much. (JSTOR seems to have more easy conditions, but when you google papers you sometimes get pointed to this site and sometimes to some other site...)
