Public domain material is by definition uncopyrighted. People can not, by definition, claim personal copyrights on public domain materials. At best, they can argue whether a certain material is in public domain or not.
Personal copyrights on openly licensed material is not something new. If I create a material and publish it under the GNU FDL license, I still have copyright on it and I'm free to distribute it under any other license that I choose to. People will be able to use my material according to the GNU FDL, or select the alternative licenses that I offer to them.
The problem is not that simple. Under US law as it now stands copyright lasts for 95 years, and that's plenty of time for lots of mischief. A lot of material gets published now with a copyright notice. Such an item may be a very long unattributed extract from a public domain source (perhaps fromWikipedia or Open-site or an obscure old book) preceded by one paragraph of original introductory material. The copyright notice doesn't make any distinction between what is original and copied material. Ten years later, when somebody uses a significant portion of that article (not from the introduction) the person who first copied it claims copyright violation. The difficulty is not with the theoretical rights that anybody has; from our vantage point these are quite clear. It is with proof, and who is in a position to defend material that is in the public domain or under GNU-FDL license from wrongful claims of copyright. Stretch that process out over a 95 year period, and the prospects are boggling!
