I just saw a post from 2008 in which Lisa Wynn, author of a paper in the Journal of Social Archaeology, complains that she was not provided with a pdf of her article by the publisher (Sage). This was posted on Culture Matters, and also on anthropologi.info. It seems that Sage provides authors with a proprietory application that allows one to print one's article on a single computer, but not save it or send it to colleagues. I guess it is just one more example of how commercial journal publishers rip off academic authors. First, they make money off of our unpaid research efforts, and second, they try to limit our own use of our intellectual products.
Several solutions come to mind. Lisa Wynn, the author in question, suggests boycotting Sage journals. I use the SPARC authors addendum, an attachment to copyright agreement with publishers. This give the author more rights than is typical with commercial publishers. Most journal publishers have gone along, but when a publisher refuses to honor the addendum, I will let you guess what I do about it.
But on a fundamental level I think authors should take their professional work into their own hands. Scan your Sage (or other) paper to create your own pdf reprint, and then post it on your website (or on Academia, edu, or on Selected Works, or anywhere you can). I notice that Lisa Wynn does not make her papers available to download on her website.
Make your work available as widely as possible, regardless of whether commercial publishers may want to limit the visibility of research they publish. Whose research is it anyway?
