Over the weekend I found an article by Daniel J. Bernstein in which he explains why he's blacklisted the IEEE and urges everyone to publish with journals that accept works dedicated to the Public Domain.
The article appears to be authored in 2005. In it Bernstein gives an overview of his attempt to get clarification from IEEE as to 1) whether they will publish articles dedicated to the Public Domain, and 2) why not if they won't. In short, despite finding that IEEE Copyright Policies allow acceptance of materials in the Public Domain, IEEE's Intellectual Property Rights Manager won't accept any papers that don't come with an assignment of copyright to the IEEE. Bernstein concludes that the IEEE's position is a "blatant attempt to maintain control over papers that would otherwise have been freely available to the public."
