I'm mostly a lurker on this list, but I worry about this as well, and have been for some time. I read this short article:
http://www.gnu.org/philosophy/right-to-read.html
in 1997 when it was first published in the Communications of the ACM (a somewhat obscure journal for academic computer scientists). I thought it was overblown then, but I'm changing my mind. The author, Richard Stallman, is a genius and a visionary, but at the same time a certifiable lunatic. He's certainly incorrect about scientific literature, which is becoming freely available more and more often with arxiv.org and plos.org.
